Ionic Bonding

Question 1

Atoms

Answer 1

• neutral
• has equal number of positive protons and negative electrons

Question 2

Ion

Answer 2

• charged element created when electrons are lost or gained
• has full outer shell

Question 3

Types of bonding

Answer 3

metallic, ionic, covalent

Question 4

metallic bonding

Answer 4

bonding between metals

Question 5

ionic bonding

Answer 5

metal and non-metals
- metals lose 1 or more electrons, become positively charged
- non-metals gain 1 or more electrons and become negatively charged

Question 6

Covalent bonding

Answer 6

non-metal and non-metal

Question 7

Cations

Answer 7

positive
-more protons and electrons
- most frequently metals

Question 8

Anions

Answer 8

negative
- most electrons then protons
- most frequently non-metals

Question 9

Transition metals

Answer 9

can lose numbers of electrons and become ions of many different charges

Question 10

Polyatomic ions

Answer 10

groups of joined non-metal atoms can gain electrons to form anions, these are called polyatomic ions

Question 11

3 polyatomic

Answer 11

Hydroxide, Carbonate, Hydrogen Carbonate

Question 12

Ionic Properties

Answer 12

High melting+ boiling points
Crystalline
Hard
Brittle (breakable)
Electrically conductive when molten or aqueous

Question 13

High melting + boiling points

Answer 13

• electrostatic attraction between cations and anions are strong
• means it takes lots of energy to break the amount of bonds in the compound

Question 14

Crystalline

Answer 14

• ionic lattus is formed due to the repeating arrangement of ions

Question 15

Brittle

Answer 15

when force is applied to twist the crystal lattice,
