5.2.1.2 Ionic Bonding

Question 1

What happens when a metal atom bonds with a non-metal atom?

Answer 1

• electrons in the outer shell of the metal atom are transferred

Question 2

What happens to a metal atom after bonding?

Answer 2

• lose electrons
• become positively charged ions

Question 3

What happens to a non-metal atom after bonding?

Answer 3

• gain electrons
• become negatively charged ions

Question 4

What happens to ions produced by metals in groups 1 and 2 and by non-metals in groups 6 and 7?

Answer 4

• gains full outer shell of electrons
• have same electronic structure as a noble gas (group 0)

Question 5

How can electron transfer during the formation of an ionic compound be respresented?

Answer 5
