orbitals?
F. Period 7
G.
Group 8A
H.
Inner transition elements
J.
Periods 4, 5, and 6

Answers

Answer:

Group 8A

Explanation:

Group 8A elements are characterized by having full outermost s and p orbitals. These elements are also known as the noble gases or inert gases. They occupy the last group on the periodic table.

They are known to have an outer shell configuration of ns² np⁶The configuration reveals that atoms of all the elements have completely filled orbitals in their outer shell sublevels. This accounts for the non-reactivity of elements in this group. Most of the elements in the group have high ionization energy and very low electron affinity values.

Some of the elements in this group are Neon, Argon, Krypton, Xenon, and Radon.

What is an ionic bond?

Answers

Answer:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion

When many earthquakes are studied, there is another common pattern that emerges: a "Shadow Zone". This is an area, for any earthquake, on the Earth where direct S-waves don't arrive at all and P waves are refracted. What do you think causes these P waves to be refracted? *

Answers

Answer:

Sudden decrease in the velocity at the boundary.

Explanation:

The shadow zone is the zone of the earth from angular distances of 104° to 140° from a known earthquake that does not directly receive any P waves. Now, this shadow zone occurs as a result of S waves getting stopped completely by the liquid core and the P waves being refracted by the liquid core.

From earlier seismic discoveries, this boundary which is the shadow zone that does not directly receive any P-waves was found to be due to the fact that the P-waves were refracted inwards as a result of the sudden decrease in velocity at the boundary.

Each of the four liquids had the same volume, why don’t
they each have the same density?

Answers

Key concepts

Physics

Chemistry

Density

Liquids

Introduction

You probably know that when solid objects are placed in liquid, they can sink or float. But did you know that liquids can also sink or float? In fact, it is possible to stack different layers of liquids on top of one another. The key is that all the different layers must have different densities. You can stack them by picking several liquids with a range of densities or by varying the density of one liquid by adding chemicals such as sugar or salt to it. If you choose colored liquids or add food coloring to each layer, you can even create a whole rainbow of colors in one single glass! Want to see for yourself? In this science activity you will stack several liquids—one by one—and create a colorful density column!

Background

Whether an object sinks or floats depends on its density compared with the density of the liquid into which it is dropped. All types of matter—solids as well as liquids—are made up of many different atoms. Depending on the mass of these atoms, their size and the way they are arranged, different substances will have different densities. The density is characteristic for each individual compound and defined as the mass of a compound divided by its volume. In other words, the more matter there is in a certain amount of volume, the denser a substance is. One cubic centimeter of rock, for example, is much heavier than a cubic centimeter of wood. This is because there is much more matter in the same volume of rock compared with the wood.

ADVERTISEMENT

Liquids can also have different densities. Freshwater, for example, has a density of about one gram per cubic centimeter at room temperature. Any compound—liquid or solid—that has a higher density than water will sink whereas substances with a lower density than that will float. You can test that for yourself by gathering several liquids that you have in your kitchen such as vegetable oil, corn syrup, dishwashing soap, water, rubbing alcohol and more. Which one of these do you think will sink or float in water? Find out in this activity!

Materials

Glass or cup

Water

Food coloring

Scissors

Rubber band (wide)

Small piece of wax

Popsicle stick

At least two small, clear jars or transparent mini cups (two ounces) with lids

Permanent marker

Masking tape

Three tablespoons

Dark corn syrup

Vegetable oil

Penny

Paper towels

Rubbing alcohol, dishwashing soap and other liquids (optional)

Sugar (optional)

Preparation

Gather all your materials at a workspace that can tolerate spills of all the liquids.

Fill a cup with tap water and add a couple of drops of food coloring to the water.

Ask an adult to help you cut and prepare small pieces (about 0.5 by 0.5 centimeter) of the rubber band, the popsicle stick and the wax.

Place the two empty jars in front of you (without the lids) and label them “1” and “2” with a piece of tape and the permanent marker.

Procedure

Take a clean tablespoon and pour two tablespoons of corn syrup in jar 1.

With the second tablespoon, carefully pour two tablespoons of colored water into jar 1 on top of the corn syrup. What happens to the water on top of the corn syrup? Does it mix or stay separate?

Use the third clean tablespoon to pour two tablespoons of vegetable oil in jar “1” on top of the colored water. Do you see mixing of the liquids? What happens to the oil? Does it float on top or sink to the bottom?

Now take empty jar 2 and add the same liquids—but in reverse order. Start by pouring in two tablespoons of vegetable oil.

Answers

Answer:

atoms tend to react in order to gain 8 valence electrons

Explanation:

The octet rule describes the tendency of atoms of elements to react in order to have eight electrons in their valence shell. This is because having eight valence electrons confers stability to the atoms of these elements in the compounds they form.

The octet rule only does not apply to the transition elements or the inner transition elements as only the s and p electrons are involved. the electronic configuration in atoms having an octet is s²p⁶.

For example, sodium atom has one valence electron in its valence shell but a complete octet in the inner shell; it will react with chlorine atom which has seven valence electrons to form a stable compound, sodium chloride by donating its one valence electron in order to have an octet. Similarly, the chlorine atom will then have an octet by accepting the one electron from sodium atom.

Water is a bent molecule with bond angles of 104.5o

Water has two pairs of unbonded electrons which are spread out evenly between the hydrogen atoms

Water’s two pairs of unbonded electrons push the hydrogen atoms further away from their negative charge

Answers

Answer:

Water is a bent molecule with bond angles of 104.5o

Water has two pairs of unbonded electrons which are spread out evenly between the hydrogen atoms

Explanation:

Water is a substance with chemical formula, H2O i.e. two hydrogen atoms bonded to one hydrogen atom. The more electronegative oxygen atom draws electron from the less electronegative hydrogen atoms to make the molecule a POLAR ONE. The water molecule assumes a bent shape with bond angle 104.5°.

The oxygen atom has two lone pairs of electrons, which each hydrogen atom is attracted to. This strong attraction forms hydrogen bonds in the water molecule. Hence, the two pairs of unbonded electrons in the water molecule are spread out evenly between the hydrogen atoms.

Why MgO will form after Mg reacting with CuO? (mcq)
Mg forms positive ions and O forms negative ions
Mg is more reactive than Cu
CuO have loose bonding

Answers

Answer:

Mg is more reactive than Cu

Explanation:

In the reaction between Mg and CuO to form MgO, MgO will form because Mg is more reactive than Cu.

This kind of reaction is called a single replacement or single displacement reaction.

The replacement of a metallic ion in solution by a metal atom higher in the activity series than the metal in solution falls into this category of reactions. The element Mg is higher than Cu in the activity series. The higher an element is in the activity series, the more reactive they are. Since Mg is more reactive, it will displace the Cu from CuO.
