Lithium, Sodium, Potassium; any of the Alkali Metals, which are farthest left on the periodic table. This is because they only have one electron in their outermost shell, so they would rather lose an electron rather than try to gain 7 to achieve that full outer shell.
The mass of an electron is:
0.00054386734 or 9.1 x <span>10^-31 kg</span><span>.

Hope it helps...
It can be done by you only
- First observe the figure or model .
- Then note the observations about its molecular structures .
- Then write it uses and why it is commercial most usable.
