1) If an element has an atomic number of 12, how many electrons are in its outermost shell?
A) 1
B) 10
C) 8
D) 2
E) 12
Answer: D
Explanation: Two electrons fill the innermost shell and eight fill the next, leaving two for the
outermost shell.

3) Which of the following subatomic particles will be found orbiting the nucleus of the atom?
A) protons and neutrons
B) only electrons
C) electrons and neutrons
D) only neutrons
E) only protons
Answer: B
Explanation: The nucleus of an atom will contain the protons and neutrons. Electrons are found
in the electron orbitals that orbit the nucleus.

4) If an element has an atomic number of 15, then
A) the atomic mass must also be 15.
B) the atom has 15 electrons.
C) there are 7 electrons in the outermost shell.
D) the atom has 15 neutrons.
E) the atom must have only one orbital.
NURSINGTB.COM
Answer: B
Explanation: In an electrically neutral atom, the number of protons (the atomic number) is the
same as the number of electrons. The atom would need three orbitals to accommodate 15
electrons, and there would be 5 electrons in its outermost shell. The atomic mass includes the
protons and the neutrons; the number of neutrons is not specified in this question.
