ionic bonding

Question 1

how ions are formed by electron loss or gain

Answer 1

Ions are electrically charged particles formed when atoms lose or gain electrons. They have the same electronic structures as noble gases (full outer shell)

Question 2

Ionic bonding

Answer 2

A strong electrostatic attraction between oppositely charged ions.

Fe3+

Question 15

Lead (II) ion

Answer 15

Pb2+

Question 16

why compounds with giant ionic lattices have high melting and boiling points

Answer 16

Ionic compounds have high melting and boiling points because they have a giant structure with strong electrostatic forces between oppositely charged ions that require a lot of energy to break.

Question 17

When does Ionic compounds conduct and doesn’t conduct electricity

Answer 17

Ionic compounds do not conduct electricity when solid, but do conduct electricity when molten and in aqueous solution
