Hope this helped!
Valence is the same in every family... except for transition metals, it goes from 1-8
dk if that helped
Answer:
Saturation.
Explanation:
Hello,
In this case, the statement is accounting for the saturation vapor pressure as it is the pressure of a vapor which is in equilibrium with its liquid, in other words it is the maximum exerted pressure possible by the vapor at a given temperature or just the maximum amount of the vapor, so there is neither no more vapor that could condense nor more liquid that could boil.

The atom present in Option (1) most likely to form cation with a charge of +1
<h3>
What is a Cation ?</h3>
A cation has more protons than electrons, consequently giving it a net positive charge.
For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
The atoms present in Option 1 have one eletron in its outermost shell therefore, it is easy for the atom to lose one elecron than more electron and to attain stable electronic confiuration.
Hence, The atom present in Option (1) most likely to form cation with a charge of +1
