Group 1

Question 1

Group 1 atoms are:

Answer 1

Alkali-metals because when they react with water they make a alkaline solution

Question 2

Reactivity

Answer 2

increases down the group

Question 3

All they reactions involve

Answer 3

The loss of one outermost electron which changes the metal atom into a metal ion

Question 4

The reactivity increases down the group because:

Answer 4

The size of the atom increases down the group because of the electron shells. This makes the attraction to the nucleus less making it easier for the valence electron to be lost.

Question 5

How many electrons do group 1 atoms have on their outermost shell?

Answer 5

1

Question 6

How does group 1 react with water?

Answer 6

It is used to decipher if an element is part of this family
Lithium, sodium and potassium react vigorously with water, producing an alkaline metal hydroxide solution
It also produces hydrogen gas which is why it fizzes
