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 valence electrons are most stable for an element in a compound (except hydrogen)?

How many electrons complete the valence shell for a Hydrogen atom?

What two types of atoms make a covalent bond?

• 2 Nonmetals
• 1 Nonmetal and 1 Metal
• 2 Metals
• 2 Noble Gases

What region of the periodic table contains atoms that form covalent bonds?

• the left side
• the middle
• the right side
• top left

In a covalent bond, one or more electrons are? 

• shared 
• lost 
• gained 
• transferred 

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
