Group 1 Metals

Question 1

Another name for group 1 metals

Answer 1

Alkali metals

Question 2

How many electrons do group 1 metals have in their outer shells?

Answer 2

One electron- gives the metals similar properties and makes them very reactive.

Question 3

Properties of group 1 elements

Answer 3

Low density
Soft

Question 4

Trends in metals as you go down group 1

Answer 4

Increasing reactivity- the outer electron is more easily lost.
Lower melting and boiling points
Higher relative atomic mass

Question 5

What charge are group 1 ions

Answer 5

1+

Question 6

What compounds do group 1 metals form

Answer 6

Ionic compounds- as they don’t need much energy to react.these compounds are generally white solids that dissolve in water to form colourless solutions.

Question 7

Group 1 metals reaction with water

Answer 7

• React vigorously to produce hydrogen gas and metal hydroxides.
• The more reactive (the lower down in the group) the metal is the more violent the reaction.
  -The amount of energy given out by the reaction increases down the group.

Question 8

Group 1 metals reaction with chlorine

Answer 8

• React vigorously with chlorine gas to form white metal chloride salts.
• as you go down the group reactivity increases so the reaction with chlorine gets more vigorous.

Question 9

Group 1 metals reactions with oxygen

Answer 9

-group 1 metals react with oxygen to form a metal oxide.
-lithium will react to form lithium oxide.

Question 10

Group 1 properties compared to transition metals.

Answer 10

• More reactive than transition metals.
• less dense
• less strong
• less hard
• lower melting points.
