Anew element is discovered that is very unstable and highly reactive, and it likes to lose its one valence electron. in what group should this element be placed in? explain.

In order to achieve the Octet rule and stability, the atom will lose or gain electron so that only eight electrons will be in the shell. These elements are placed in the group 1 or A of the periodic table. The group is comprised of the hydrogen and the alkali metals. 

Man i dont know this answer

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
