A sealed cylinder is filled with a large collection of atoms that have 14 neutrons and 13 protons. Which of the following would behave in a manner similar to this collection of atoms?
A)a group of atoms with 13 neutrons and 14 protons
B)a group of atoms with 14 neutrons and 15 protons
C)a group of atoms with 15 neutrons and 14 protons
D)a group of atoms with 15 neutrons and 13 protons

Question

Quizplus · Accepted Answer

Atoms with 13 protons are aluminum atoms. The number of neutrons can vary, creating isotopes, but the chemical behavior is determined by the number of protons. Thus, a group of atoms with 15 neutrons and 13 protons would behave similarly.
