C3.3 - Ionic bonding

Question 1

What do you probably not think about, when you eat salty food?

Answer 1

When you eat salty food, you probably do not think about the charged particles that enter your body

Question 2

When are ionic compounds usually formed?

Answer 2

Ionic compounds are usually formed when metals react with non-metals

Question 3

Ionic compounds are usually formed when metals react with non-metals.
What is it that form positive ions and negative ions?

Answer 3

It is the:

1. Metals that form positive ions
2. Non-metals that form negative ions

Question 4

Ionic compounds are usually formed when metals react with non-metals.
How are the ions formed held together?

Answer 4

The ions formed are held next to each other by very strong forces of attraction between the oppositely charged ions

Question 5

Ionic compounds are usually formed when metals react with non-metals.
The ions formed are held next to each other by very strong forces of attraction between the oppositely charged ions.
What is this electrostatic force of attraction called?

Answer 5

This electrostatic force of attraction is called ionic bonding

Question 6

Ionic compounds are usually formed when metals react with non-metals.
The ions formed are held next to each other by very strong forces of attraction between the oppositely charged ions.
This electrostatic force of attraction, which acts in all directions, is called ionic bonding.
What does the ionic bonds between the charged particles result in?

Answer 6

The ionic bonds between the charged particles results in an arrangement of ions called a giant:
1. Structure
Or,
2. Lattice

Question 7

Giant structure or giant lattice

Answer 7

A giant:
1. Structure
Or,
2. Lattice
is a huge 3D network of atoms or ions

Question 8

When atoms form ionic bonds, what do atoms from group 3 do, when they form ions as opposed to sharing elections?

Answer 8

When atoms form ionic bonds, atoms from group 3 form 3+ ions, when they form ions as opposed to sharing electrons

Question 9

When atoms form ionic bonds, what do atoms from group 4 do?

Answer 9

When atoms form ionic bonds, atoms from group 4 do not form ions, apart from:

1. Tin
2. Lead

Question 10

When atoms form ionic bonds, what do atoms from group 5 do, when they form atoms as opposed to sharing electrons?

Answer 10

When atoms form ionic bonds, atoms from group 5 form 3- ions, when they form atoms as opposed to sharing electrons

Question 11

When atoms form ionic bonds, what do atoms from group 6 do, when they form ions as opposed to sharing electrons?

Answer 11

When atoms form ionic bonds, atoms from group 6 form 2- ions, when they form ions as opposed to sharing electrons

Question 12

When atoms form ionic bonds, what do atoms from group 7 do, when they form ions as opposed to sharing electrons?

Answer 12

When atoms form ionic bonds, atoms from group 7 form 1- ions, when they form ions as opposed to sharing electrons

Question 13

When atoms form ionic bonds, what do atoms from group 8 or group 0 do?

Answer 13

When atoms form ionic bonds, atoms from group 8 or group 0 never form ions in compounds

Question 14

Examples of ionic bonding

Answer 14

Examples of ionic bonding are:

1. Magnesium oxide
2. Calcium chloride
3. Sodium chloride
4. Calcium oxide

Question 15

When you eat salty food, you probably do not think about the charged particles, called what that enter your body?

Answer 15

When you eat salty food, you probably do not think about the charged particles, called:
1. Sodium ions
2. Chloride ions
,that enter your body
