Periodic Table Basics

The order of elements in the periodic table is based on

• the number of protons in the nucleus

• the electric charge of the nucleus.

• the number of neutrons in the nucleus

• atomic mass.

Atoms of elements that are in the same group have the same number of

• Protons

• Neutrons

• valence electrons

• protons and neutrons

Each column of the periodic table is

• a period

• a notation

• a group

• an isotope

Each row of the Periodic Table is

• a period

• a notation

• a group

• an isotope

Elements that share properties of both metals and nonmetals are called

• Ions

• Metalloids

• Periods

• valences

Which of the following properties describe metals?
