A neutral atom of nitrogen has electrons in energy level(s):
Select one:
O a. 1 only
O b. 2 only
O c. 1 and 2
O d. 1, 2, and 3
Answer:
c
Explanation:
Nitrogen is in period 2, and has electrons in both 1 and 2.
The electron seeks to go up to energy level n = 2 from level 1, which is the initial energy level. Since the second energy level has more energy than the first, the electron must gain energy to travel from n = 1 to n = 2. A neutral atom of nitrogen has electrons in energy levels are 1 and 2.
What is energy level ?Any discrete value from a set of total energy values for a subatomic particle constrained by a force to a finite space or for a system of such particles, such as an atom or a nucleus, is referred to as the energy level, also known as the energy state, in physics.
"Energy levels" refer to the areas around the nucleus where an atom's electrons are positioned. The 3-dimensional region around the nucleus where electrons are most likely to be is represented by an energy level.
Every component of the cycle of wellness depends on energy. Our attitude and physical health both get better as we get more energy. Connecting with people, exercising, and feeling driven to work hard and accomplish personal objectives are all more likely.
Thus, option C is correct.

An atom contains 16 protons, 18 neutrons, and 16 electrons what is its mass number?
Name the element of which this is an isotope.
16
protons
18
neutrons
16

Right from the start, you know that you're indeed dealing with a neutral atom, since the number of protons it has in its nucleus is equal to the number of electrons it has surrounding its nucleus.
Now, an atom's atomic number,
Z
, tells you how many protons it has in its nucleus. Nothing more, nothing less.
In your case, you are told that the atom contains
16
protons in its nucleus, which means that
Z
will be equal to
Z
=
16
A quick look in the periodic table will reveal that you're dealing with an atom of sulfur,

A student measured the mass of some sodium chloride for a lab. the lab called for 6.25 g (the accurate measurement ) , but the student measured 6.00 g instead . what is the percent error for this mass ? Show your work .
Answer:
The answer is
[tex] \huge 4\%[/tex]
Explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question
actual mass = 6.25 g
error = 6.25 - 6 = 0.25
So we have
[tex]p(\%) = \frac{0.25}{6.25} \times 100[/tex]
We have the final answer as

A fluorescent light tube has an internal volume of 400 cm and an internal pressure of 200 kPa.
It is filled with 0.03 moles of an ideal gas.
What is the temperature of the gas inside the fluorescent light tube?
A 3.21 x 10 K
B 3.21 x 10?K
с 3.21 x 105K
D 3.21 x 10K
with explanation plz
Answer:
Temperature of gas is 3.21×10² K
Explanation:
Given data:
Volume of bulb = 400 cm³ (400/1000 = 0.4L)
Pressure of bulb = 200 KPa (200/101= 1.974 atm)
Number of moles of gas = 0.03 mol
Temperature of gas = ?
Solution:
Formula:
PV = nRT
R = general gas constant = 0.0821 atm.L/ mol.K
1.974 atm × 0.4 L= 0.03 mol × 0.0821 atm.L/ mol.K × T
0.7896 atm.L = 0.002463 atm.L/K × T
T = 0.7896 atm.L / 0.002463 atm.L/K
T = 321 K 0r 3.21×10² K

How many centimeters are in 1 inch?
The metric system is used to measure the objects based on various parameters. A centimeter is a unit of length. One inch is equivalent to 2.54 cms.
What is the metric system?The Metric system is the system used to estimate the weight (mass), length, and capacity of the object and was first introduced in France by Gabriel Mouton, a mathematician, and an astronomer. The metric system measures length, mass, volume, time, etc.
The metric system of length use the SI unit of meter, other units used to measure the length are centimeter, kilometer, millimeter, inches, yard, mile, feet, etc.
Given,
Length = 1 inch
It is known that an inch is equivalent to 2.54 centimeters, hence, 1 cm = 2.54 cms.
Therefore, there are 2.54 centimeters in one inch of the object.

how would you describe the size of atoms and molecules in your own words ?
Answer:
tomic size is the distance from the nucleus to the valence shell where the valence electrons are located. Atomic size is difficult to measure because it has no definite boundary. The electrons surrounding the nucleus exist in an electron cloud.
Explanation:
Answer:
Atomic size is the distance from the nucleus to the valence shell where the valence electrons are located. The separation that occurs because electrons have the same charge. The number of protons in the nucleus. The core electrons in an atom interfere with the attraction of the nucleus for the outermost electrons. and Molecular size is a measure of the area a molecule occupies in three-dimensional space. The amount of space any mass takes up in three-dimensional space is known specifically as its volume.
A fluoride ion (F) has the same electron configuration as
A. Na+
B.Na
C.Cl-
D.Cl
Answer:
Option A. Na⁺
Explanation:
Floride ion (F¯) simply indicates that the fluorine atom has gain an extra electron.
Thus, the electronic configuration of the fluoride ion (F¯) can be written as follow:
F¯ (10) => 1s² 2s²2p⁶
Next, we shall determine the electronic configuration of the element given in options to see which is the same as that of the fluoride ion (F¯). This is illustrated below:
Na⁺ (10) => 1s² 2s²2p⁶
Na (11) => 1s² 2s²2p⁶ 3s¹
Cl (17) => 1s² 2s²2p⁶ 3s²3p⁵
Cl¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶
From the above illustrations, we can see that the fluoride ion (F¯) has the same electronic configuration as Na⁺.
Each element is made up of electrons and these electrons are filled in different shells. These are the following shells in the electrons:
K shellL shellM shellN shellAccording to the question, the fluoride ion has 10 electrons in its 2 shells, that is 2 in K shell and 8 in L shell.
A similar number of shell and electrons to the fluoride ion is sodium ion ([tex]Na^{+}[/tex])
The [tex]Na^+[/tex]has a total 10 number of electrons, hence the electronic configuration is 2 and 8.
Therefore, the [tex]Na^+[/tex] is the correct option.

Answer:
The given sample is aluminum.
Explanation:
Given data:
Mass of unknown sample = 54 g
Volume of given sample = 20cm³
Is sample is Al = ?
Solution:
In order to solve this problem we must know the density of Al from literature.
density of Al = 2.7 g/cm³
Now we will calculate the density of given unknown sample.
d = m/v
d = 54 g/ 20cm³
d = 2.7 g/cm³
Thus given sample is aluminum.
