# What elements are found to the left of the staircase and form ionic bonds with non-metals, give away electrons and become positive? Hydrogen is the exception.

You refer to the $\text{Periodic Table............}$

#### 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 $\text{alkali metals}$. These are soft shiny metals; very reactive; and they act to reduce water:

$M \left(s\right) + {H}_{2} O \left(l\right) \rightarrow {M}^{+} \left(a q\right) + H {O}^{-} \left(a q\right) + \frac{1}{2} {H}_{2} \left(g\right) \uparrow$

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