Section 4 - Covalent Bonding

Question 1

Which type of elements is covalent bonding for?

Answer 1

The ones with half-full shells

Question 2

What is a covalent bond?

Answer 2

A covalent bond is a shared pair of electrons

Question 3

Describe how covalent bonding works

Answer 3

Elements with half-full shells share their electrons with another atom so they’ve both got a full outer shell. Both positive nuclei are attracted to the shared pair of electrons. This results in the formation of covalent bonds

Question 4

Wha is a multiple covalent bond?

Answer 4

A bond that forms when two atoms share more than one pair of electrons between them

Question 5

What is an example of a molecule with a multiple covalent bond?

Answer 5

Carbon Dioxide

Question 6

Describe dative covalent bonds

Answer 6

In dative covalent bonds, both of the shared electrons in the covalent bond come from the same atom

Question 7

What can dative covalent bonds be shown by?

Answer 7

An arrow pointing away from the ‘donor’ atom
