Answer:
Cation
Explanation:
In a polar reaction mechanism, a specie must give out electrons and another specie must accept those electrons.

Hence, the specie that looses electrons becomes a cation.
The valence of an atom is defined as the number of bonds formed by the atom in the molecule.
The given atomic number is 7.
The electronic configuration of atom having atomic number 7 is:
From the electronic configuration, it is clear that number of electrons in the outer most orbital (valence shell electron) is 5.
Hence, for an atom whose atomic number is 7. Its valence is 5.
