Answer:

Explanation:

1

When elements in group 2 react with Iodine, a salt MI_2 is formed

2

When they react with water, Hydrogen gas is released

3

When they react with Oxygen, an Oxide, MO is formed

4

The most vigorously reactive metal in group 2 is Barium, Ba. Reactivity increases as one moves downward in group 2

5

The most metallic element is Barium, Ba. This is because in the periodic table, metallic strength of metals increases as one moves down the table.

The thing that happens when the elements in group 2 react with iodine is:

The way these elements react with water is:

The way they react with oxygen is:

The element which reacts the most vigorously in group 2 is:

Barium, Ba. This is because their reactivity increases as one moves downward in group 2

The element in the group which is the most metallic in character is:

Barium, Ba. It is this way because of the changes in metallic strength as metals change positions in the table
