Ionic Bonding

Question 1

What is an atom?

Answer 1

The smallest particle of an element that contains electrons surrounding a nucleus

Question 2

What is a molecule?

Answer 2

A molecule is a group of two or more atoms chemically combined

Question 3

How are ions formed?

Answer 3

Electron loss or gain

Question 4

What are group 1,2 and 3 elements and what charge are they?

Question 14

What charge are carbonate ions?

Answer 14

CO3 2-

Question 15

What charge are nitrate ions?

Answer 15

NO3-

Question 16

What charge are sulfate ions?

Answer 16

SO4 2-

Question 17

What is ionic bonding in terms of electrostatic attraction?

Answer 17

The electrostatic force of attraction between a positively charged metal ion and a negatively charged non-metal ion

Question 18

Why do compounds with giant ionic lattices have high melting and boiling points?

Answer 18

Electrostatic forces are very strong so a lot of energy is needed to break the forces.

Question 19

Why can ionic compounds only conduct electricity when molten and in aqueous solution?

Answer 19

Only then are the ions of the compound able to move around carrying a charge. A sea of delocalized electrons.
