Ionic and Covalent Compounds

1) What is the chemical formula?

2) How many valence electrons are being shared total?

3) How many valence electrons are NOT being shared?

4) What type of bond is between H and O? Single? Double? Triple?

5) Are each of the atoms happy? (yes or no)

1. Look at the examples above. How many bonds does hydrogen form?

2. Hydrogen ALWAYS forms this number of bonds. Why?

Station 5

ONE

It only needs one more electron to have a full outer shell

4) Compounds have a total charge of zero 5) Atoms share electrons

3) Atoms transfer electrons

Ionic Compounds Covalent Compounds

2) Atoms in the compound have charges that balance out.

6) Formed when one atom wants to gain and one atom wants to lose electrons

1) Formed when one or more atoms want to gain electrons
