Isotopes and Ions

Multiple Choice

An atom that has more protons then electrons are called

• cations

• anions

• isotopes

• molecules

Isotopes are atoms with the:

• same atomic number

• same number of protons

• same number of electrons

• same identity/symbol/name

• different number of nuetrons

Multiple Choice

Isotopes are atoms with a different number of

• protons

• electrons

• neutrons

• atoms

Multiple Choice

This particle determines the identity of an atom

• proton

• neutron

• ion

• isotope

Ions are atoms that have either:

• gained electrons

• lost electrons

• 
  

• 
  

• 
  

Atoms that have lost electrons

• are called Cations

• have a positive charge

• have more protons than electrons

• are metals

Atoms that have gained electrons

• are called Anions

• have a negative charge

• have more electrons than protons

• are non-metals

Multiple Choice

These form when atoms gain or lose electrons:

• isotopes

• ions

• atoms

• electrons

Multiple Choice

This particle determines the charge of an atom?

• proton

• electron

• neutron

• ion

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
