Answer I need help please it’s hard

No. of proton=3

No. of electron =3

No. of neutron=4

●Atm no. = no. of protons (always)

THEREFORE Atm no.=3

●No.of p= no. of e (Neutral atom)

hence here no. of p = no. of e =3 Therefore it is Neutral atom

●Mass No.=no. of p + no of neutron

Massno.=3+4=7

So Atm no.=3

Mass no.=7

Therefore it is Li atom.

Net charge=0( as no. of p= no. of e)

THANK YOU.
