Ions and Isotopes

Isotopes and Ions

Isotopes are atoms with:

• same atomic #

• same number of p+

• same number of e-

• same identity/symbol/name

Ions: atoms that have gained or lost electrons

Atoms that lose e-

• Cations

• Positively charged

• have more p+ than e-

• are metals

Atoms that gain e-

• Anions

• Negatively charged

• have more e- than p+

• are non-metals

Multiple Choice

These form when atoms gain or lose electrons:

• isotopes

• ions

• atoms

• electrons

Multiple Choice

Potassium is a metal, therefore it will

• lose electrons

• gain electrons

Multiple Choice

Sulfur is a non-metal, therefore it will:

• become an anion

• became a cation
