Ions And Ionic Compounds

Question 1

Cation:

Answer 1

Positively charged ion ( removing electron )

Metals will lose electrons thereby forming cation.

Question 2

Anion:

Answer 2

negatively charged ion ( adding electron )

Non metals tend to gain electrons thereby forming anion

Question 3

Ion:

Answer 3

An electrically charged atom.

Question 4

Ionic bonding

Answer 4

: is one of the ways atoms can form compounds

Question 5

Ionisation energy:

Answer 5

” energy required to remove 1 electron from each atom atom in 1 mole of gaseous atoms to form 1 mole of gaseous”

Question 6

Electrolysis:

Answer 6

Electric current is used to break down a substance made up of ions.

Question 7

Electrolyte

Answer 7

Is the name for the substance being broken down.

Question 8

P. A. N. I. C

Answer 8

Positive anode negative cathode

Question 9

Cathod:

Answer 9

Negative electrode

Question 10

Anode

Answer 10

Positive cathod

Question 11

Properties of ionic bounding.

Answer 11

High melting point and high boiling.

Dissolve easily in water. The ions separates and are free to move this creating a electric current.

Question 12

Ionic compounds:

Answer 12

Giant lattice

Strong electrostatic forces of attraction; between oppositely charged ions (all directions)

Question 13

Aluminium oxide electrolysis.

Answer 13

Molten aluminum oxide_ created - dissolving the aluminum in molten cryolite.

This forms the electrolyte - through which energy can pass- this causes the aluminum oxide to split into aluminum and oxygen

Question 14

Gaining electrons is reduction

Answer 14

The positives are reduced

Question 15

Losing electrons :

Answer 15

Is oxidization

Question 16

Mole:

Answer 16

A unit to describe a number of atoms
6.022 x 10(23)
Avagadros number
= IE: KJmol-1
