When two atoms share six electrons with one another, the type of bond do they form is: D. a triple covalent bond.
A covalent bond can be defined as a bond that exists in chemical compounds and it typically involves the sharing of electrons between the atoms of a non-metallic chemical element.
In Chemistry, there are three (3) main types of covalent bond and these include:
A single covalent bondA double covalent bondA triple covalent bondA triple covalent bond is a type of covalent bond that is formed when the two (2) atoms of a non-metallic chemical element share six electrons with one another instead of the usual two in a single covalent bond.
In conclusion, a triple covalent bond is usually stronger than the equivalent single covalent bond and double covalent bond.

The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.
Beta radiations:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminum is used to block the beta radiation
_______________ are filled with special absorbing elements that move up and down between the uranium rods to keep the atoms from getting out of control.
Answer:
The correct answer is - control rods.
Explanation:
Control rods are filled with special absorbing agents such as boron, cadmium, silver, and others to absorb as many neutrons as to control the fission reaction by moving them up and down in between uranium rods.
These control rods are used to prevent the nuclear reaction from getting out of control in the nuclear plant or reactor by absorbing the neutrons and prevent uranium to convert.
what is the overall charge of an atom.
Overall, an atom is neutral charged. The Bohr model was for years accepted as the final authority because it agrees so well with experiment and observation. In this model an atom consists of a nucleus containing protons and neutrons. The neutrons are zero charge so we can forget them in looking for charges. For each proton (1 positive charge) there is always 1 electron (1 negative charge) in orbit around the nucleus. thus an atom has a equal number of electrons and protons and their net charge is zero.
We can do things to temporarily up set this natural balance (we call this electricity) but the atoms will eventually return to their naturally balanced state

According to the Kinetic Molecular Theory, why does an increase of temperature cause an increase of pressure in a closed container?
The particles move faster and hit the walls of the container more often.
The particles move faster and hit the walls of the container more often.
The particles become larger and hit the walls of the container more often.
The particles become larger and hit the walls of the container more often.
The particles react more and hit the walls of the container more often.
The particles react more and hit the walls of the container more often.
The particles break apart and hit the walls of the container more often.
Answer:
According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.

Would you classify the atoms in the table as pure substances?
Answer:
Yes
Explanation:
Atoms are generally classified as pure substances. A pure substance has the following properties:
All parts are the same throughout i.e. homogeneousThey have definite compositionThe cannot easily be broken down into simpler substances by physical means. Separation by physical methods is not easy. They have unique sets of physical properties.Elements and compounds are generally classified as pure substances. Since atoms are the building blocks of pure substances, they can be classified as one.

How many micrograms (ug) are in 3.4 x 10^-5 ounces (oz)
Answer:
964ug
Explanation:
The problem here involves converting from one unit to another.
We are to convert from ounces to micrograms.
1ug = 1 x 10⁻⁶g
1oz = 28.35g
So we first convert to grams from oz then take to ug:
Solving:
1oz = 28.35g
3.4 x 10⁻⁵oz will then give 3.4 x 10⁻⁵ x 28.35 = 9.64 x 10⁻⁴g
So;
1 x 10⁻⁶g = 1ug
9.64 x 10⁻⁴g will give [tex]\frac{9.64 x 10^{-4} }{1 x 10^{-6} }[/tex] = 9.64 x 10²ug or 964ug
