An atom that gains or loses an electron becomes

• an isotope

• a new element

• an ion

• a molecule

When an atom gains an electron it becomes

• negatively charged

• positively charged

• neurtal

Most elements bond to create compounds because

• their outer electron level is full

• they are unstable

• they are positively charged
