Answer:

You refer to the #"Periodic Table............"#

Explanation:

And a copy should be in front of you now if you are doing your chemistry or physics homework.

Look at the Table, look at the left most column. You find a column of metals: lithium; sodium; potassium; rubidium; caesium; francium. In some Tables, hydrogen often shares their Group.

Collectively, these are known as the #"alkali metals"#. These are soft shiny metals; very reactive; and they act to reduce water:

#M(s) + H_2O(l) rarr M^(+)(aq) + HO^(-)(aq) + 1/2H_2(g)uarr#

You should report back on the atomic numbers of these metals.
