Question 1 of 8
1. Question
Which of the following indicates the number of protons and neutrons in an atom with an atomic number of 6 and a mass of 14?
Correct
The atomic number reflects the number of protons in the atom. So, an atom with an atomic number of 6 would have 6 protons. The mass number reflects the number of protons and neutrons added together. So, an atom with 6 protons and a mass number of 14 would have 14 – 6, or 8, neutrons.

Question 3 of 8
3. Question
What is the approximate overall mass of an atom with 19 protons and 23 neutrons?
Correct
The approximate overall mass of an atom, in AMU, is equal to the number of protons plus the number of neutrons. The approximate overall mass of this atom is 19 + 23, or 42, AMU.
Incorrect
The approximate overall mass of an atom, in AMU, is equal to the number of protons plus the number of neutrons. The approximate overall mass of this atom is 19 + 23, or 42, AMU.

Question 4 of 8
4. Question
What are the overall charge and mass number of an atom with 6 protons, 8 neutrons, and 7 electrons?
Correct
The overall charge is –1, and the mass number is 14. The charge is calculated by determining the difference between the number of protons and electrons. In this case, there are 7 electrons and 6 protons, which means that the atom has 1 more electron than the number of protons. The overall charge is therefore –1. The mass number is the number of protons plus the number of neutrons: in this case, 6 + 8 = 14.

Question 5 of 8
5. Question
In the model of an atom shown above, label B reflects which of the following if it is a positively charged atomic particle?
Correct
Protons are positively charged atomic particles. In the model shown, label B indicates a proton.
Incorrect
Protons are positively charged atomic particles. In the model shown, label B indicates a proton.

Question 6 of 8
6. Question
The mass and electrical charge of a neutron can best be described by which of the following statements?
Correct
Protons and neutrons have approximately the same mass, and neutrons have a neutral charge. Electrons are much smaller in mass than protons and neutrons.
Incorrect
Protons and neutrons have approximately the same mass, and neutrons have a neutral charge. Electrons are much smaller in mass than protons and neutrons.

Question 7 of 8
7. Question
Which of the following reflects the overall charge of an atom with 10 protons, 12 neutrons, and 11 electrons?
Correct
In an atom, protons are positively charged, and electrons are negatively charged. When an atom has an equal number of protons and electrons, its overall charge will be neutral. When the atom has more electrons than protons, its overall charge will be negative. This atom has 11 electrons and 10 protons, so its overall charge is negative. The number of electrons exceeds the number of protons by 1, so the overall charge is –1.

Question 8 of 8
8. Question
Which of the following indicates the number of protons in an atom with an atomic number of 21 and a mass number of 55?
Correct
The atomic number of an atom reflects the number of protons in the atom. This atom has an atomic number of 21, so it has 21 protons.
Incorrect
The atomic number of an atom reflects the number of protons in the atom. This atom has an atomic number of 21, so it has 21 protons.
