Which one of the atoms shown would most likely form a cation with a charge of +1

The atom present in Option (1) most likely to form cation with a charge of +1
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
