Draw a sodium ion.

3

Group 1 metals react with what to form an ionic compound?

Non-metal

4

What is the electronic configuration for a magnesium ion?

2, 8

5

What group in the periodic table has the same electronic configuration as ions?

0 Noble Gases

6

Describe how a calcium ion is formed.

Loses 2 outer electrons

7

What is the charge on a potassium ion?

+1

How is a chloride ion formed?

Gains 1 outer shell electron

9

What do group 7 elements react with to form an ionic compound?

Metals

10

What is the charge on an oxide ion?

O2-

11

What is an ion?

A charged particle

12

What is an ionic compound?

Metal & Non-metal chemically bonded

13

What charge will group 1 elements form?

+1

14

What charge will the halogens form?

-1

15

What is ionic bonding?

Electrostatic attraction between ion formed by the transfer of electrons

16

Ionic compounds have what type of boiling and melting points? Why?

High, because they are lattice structure so ionic bonds would have to be broken

17

When melted or dissolved in water ionic compounds conduct electricity, why?

Ions are free to move

18

What is the formula of methane?

 CH4

19

What are represented by ?

Shared pair of electrons – covalent bond

20

What type of bonding is found in methane?

Covalent

21

Why do simple molecules evaporate easily?

Weak intermolecular forces don’t need a lot of energy  to break

22

What group of elements don’t often bond because they are unreactive?

0 – Noble Gases

23

What type of bonding is found in compounds with metals and non-metals?

Ionic

24

What type of bonding is found in C2H6?

Covalent

25

What type of bonding is found in potassium bromide?

Ionic

26

What is the formula of potassium bromide?

KBr

27

Explain in terms of electron transfer how potassium bromide is bonded?

 1 outer electron is transferred from potassium to the bromine to form ions which attract

28

Draw a hydrogen molecule.

29

Draw a chlorine molecule

30
