(B) The number of protons in an atom is equal to its atomic number. Here,the atomic number is $3$,which corresponds to the element Lithium $(Li)$.Since the atom is neutral,the number of electrons is equal to the number of protons,which is $3$.The electronic configuration of this atom is $2, 1$.Since the number of electrons in the outermost shell (valence shell) is $1$,the atom will lose $1$ electron to achieve a stable octet configuration.Therefore,the valency of the atom is $1$.

An atom with $3$ protons and $4$ neutrons will have a valency of
