Covalent Bonding

Which of the following describes the process of creating a covalent bond?

• Bonds form because of opposite charges

• Bonds form to fill valence electron shells

• Electrons are transferred between atoms

• Magic

In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.

• electrons are completely transferred between two metals.

• pairs of electrons are shared between two nonmetal atoms.

• two nonmetal atoms are attracted to each other by opposite charges.

How many electrons form a bond?

After drawing in your bonds, what do you do if you don't have enough electrons to get each atom to its octet?

• Place dots until everything has eight

• Place dots only around the terminal atoms

• Share two more electrons between atoms to get up to 8 creating a multiple bond.

• Have eight only around the central atom
