What are valence electrons?
The number of electrons in the outer shell that an atom can lose/gain
What type of elements form Covalent Bonds?
Nonmetal + Nonmetal
What type of elements form Ionic Bonds?
Metal + Nonmetal
Where are metals found on the periodic table?
Left of the stairstep line.
Where are nonmetals found on the periodic table?
Right of the stairstep line, but Hydrogen is found above Alkali Metals.
Name this compound:
(NH4)3PO4
Ammonium Phosphate
What happens to valence electrons in a covalent compound?
they are shared between the atoms
What happens to valence electrons in a ionic compound?
The electrons are stolen. One atom loses electrons and the other one gains them.
What type of ions are formed by metals?
Positive (Cations)
What type of ions are formed by nonmetals?
negative (Anions)
SO4
Sulfate; -2
