Covalent Bonding

Question 1

-When does a covalent bond form?

Answer 1

-A covalent bond forms when two non-metal atoms share a pair of electrons in the outer shell.

Question 2

-What are some properties of covalent bonds?

Answer 2

• Covalent bonds are very strong meaning a lot of energy is required to break them.
• They have low melting and boiling points.
• Have weak intermolecular forces between molecules; meaning only a small amount of heat energy is required to separate the molecules.

Question 3

-How many bonds can covalent bonds share?

Answer 3

-Covalent bonds can share not only one but two or more pairs of electrons.

Question 4

-How do you work out how many covalent bonds an element will form?

Answer 4

-8 minus the elements group number.
