Asemmisa {{asɛmmisaAhyɛnsode}}

4.

Use the words below in order to fill in the blanks in the paragraph below:

Hydrogen Soft Violently Very Hydroxide More Down

Alkali metals are in group 1 of the periodic table. Unlike other metals, they are and are easy to cut. They are reactive and therefore need to be stored in oil. They will react with water, producing a metal and gas. The further the group the reactive the metal is.
