Metals And Non Metals

Question 1

What bonding do all metals have?

Answer 1

Metallic bonding

Question 2

List the properties of metals

Answer 2

Very strong bonds
Malleable
High boiling and melting point
Good conducts of energy and heat

Question 3

List the proporties of group 1 alkaline metals

Answer 3

Low boiling point
Soft
Low density
More reactive

Question 4

How do the reactivity of the group 1 alkaline change as you down the group?

Answer 4

It increases

Question 5

How does the melting points and boiling points change as you go down the group?

Answer 5

They decrease

Question 6

Why are Group 1 alkaline metals so reactive?

Answer 6

This is because they easily lose only one electron on its outermost shell

Question 7

Why does the reactivity increase as you go down the group?

Answer 7

This is because the forces of attraction between the positive nucleus and electron are further away the more you go down the group meaning it easily loses its electron

Question 8

What do you get when you react an alkali metal with water

Answer 8

Alkali metals + Water —> Metal Hydroxide + Hydrogen Gas

Question 9

Describe the properties of the group 7 halogen fluorine

Answer 9

Poisonous yellow gas which is very reactive

Question 12

Describe the properties of Iodine

Answer 12

Dark grey poisonous solid

Question 13

What happens the BP and MP and reactivity of the group 7 halogens as you go down the group?

Answer 13

MP BP increase

Reactivity decreases
