1.1 - Chemical bonding

Question 1

What are the two ways atoms join together to form compounds?

Answer 1

1) Sharing electrons (covalent bonding)

2) Transferring electrons to achieve stable electronic structures (ionic bonding)

Question 2

Describe the structure of a noble gas

Answer 2

They have stable electronic structures

Question 3

How many electrons occupy the highest occupied energy level in a group 1 element?

Answer 3

1 electron

Question 4

How many electrons occupy the highest occupied energy level in a group 7 element?

Answer 4

7 electrons

Question 5

Describe the combining of group 1 and group 7 elements (3)

Answer 5

• atoms of metals in group 1 combine with non-metals in group 7
• by transferring electrons
• to form ions that have the electronic structures of noble gases
