Ionic Bonding

Question 1

How are ions formed?

Answer 1

By gaining or losing electrons

Question 2

Ionic bonding happens between a

Answer 2

Metal and non-metal

Question 3

To …

Answer 3

Achieve a full outershell

Question 4

Metals …. electrons to become …. charged

Answer 4

Loose

Positively

Question 5

Non-metals … electrons to become …. charged

Answer 5

Gain

Negatively

Question 6

The charge of an ionic compound is

Answer 6

Neutral

Question 7

Charges on an ionic compound must always be ….

Answer 7

Equal

Question 8

Rules for naming a metal + nonmetal compound

Answer 8

Metal + non-metal + ‘ide’
First and second bit stays the same but add ‘ide’ when there are two elements in the compound
But +’ate’ if oxygen is present

Question 9

Do elements have an overall charge?

Answer 9

NO!

Question 10

What are the prefixes for some non-metal compounds

Answer 10

1. Mono
2. Di
3. Tri
4. Tetra

Question 11

How can you find the charge of an element?

Answer 11

Look at its group in the periodic table and if it’s a metal than its charge is whatever that elements group is with a + next to it
If it’s a non-metal than it’s just the same but with a -

Question 12

What is an ionic compound in terms of structure?

Answer 12

A giant structure of ions

Question 13

How is an ionic compound held together?

Answer 13

By the strong electrostatic forces of attraction between oppositely charged ions

Question 14

What is the charge of the ion that transitions metals usually make?

Answer 14

Usually for 2+ ions

Question 15

Describe ionic bonding in terms of electrostatic attractions

Answer 15

● A giant structure of ions = ionic compound
● Held together by strong electrostatic forces of attraction between oppositely
charged ions
● The forces act in all directions in the lattice, and this is called ionic bonding.

Question 16

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

Answer 16

● Strong electrostatic forces of attraction between oppositely charged ions
● Requires a lot of energy to overcome these forces of attraction
● Therefore, the compounds have high melting and boiling points

Question 17

Explain why ionic compounds do not conduct electricity when solid, but do conduct electricity when molten and in aqueous solution

Answer 17

● As a solid, the ions are in fixed positions so can’t conduct electricity
● when molten or in aqueous solution the ions are free to move carrying charge
and conducting electricity

Question 18

What is a cation

Answer 18

positive​ ​ion​ ​(+​ ​→​ ​ca+ion)

Question 19

What is an anion

Answer 19

negative​ ​ion​ ​(Negative​ ​→​ ​aNion)
