PS8 Matter II Unit Test Review

Mason is studying chemistry and wants to know the atomic number of an element. It equals the number of

• protons only.

• neutrons only.

• protons and neutrons combined.

• electrons only.

In a science class, Arjun is asked to determine the atomic mass of an element. He knows that the atomic mass equals the number of

• protons only.

• neutrons only.

• protons and neutrons combined.

• electrons only.

During a science class, Zoe and Nora are discussing how the periodic table is arranged. How is it organized?

• by increasing atomic number

• by atomic mass

• by the number of neutrons

• by state of matter

Avery and Isla are comparing elements in the periodic table. They notice that elements in the same group

• have the same number of protons.

• have the same atomic mass.

• have the same number of energy levels in the electron cloud.

• have the same number of valence electrons.

Luna and Isla are comparing elements in the same period of the periodic table. What do these elements have in common?

• have the same number of protons.

• have the same atomic mass.

• have the same number of energy levels in the electron cloud.

• have the same number of valence electrons.
