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

ionic bonding

Answer 4

Between metal & non-metal atoms
- metals lose 1 or more electrons, become + charged
- non-metals gain electrons and become - charged

Question 5

Cations

Answer 5

positive
-more protons than electrons
- mostly metals

Question 6

Anions

Answer 6

negative
- more electrons then protons
- mostly non-metals

Question 7

Transition metals

Answer 7

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

Question 8

Polyatomic ions

Answer 8

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

Question 9

3 polyatomic

Answer 9

Hydroxide, Carbonate, Hydrogen Carbonate

Question 10

Ionic Properties

Answer 10

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

Question 11

High melting + boiling points

Answer 11

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

Question 12

Crystalline

Answer 12

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

Question 13

Brittle

Answer 13

when force is applied to twist the crystal lattice,
