Answer:
A. Element Name: Flourine
no. of electrons (e^-)=Atomic number (Z)=no. of protons (p^+)
no. of neutrons (n^0)=Atomic mass-no. of protons (p^+) i.e. (n^0)=10
B. Element Name: Neon
Atomic mass=no. of electrons/protons + no. of neutrons i.e. 10+10=20
no. of protons (p^+)=no. of electrons (e^-)=Atomic number (Z)=10
Charge= -2
Explanation:
Charge is the tendency of an atom to lose or gain an electron. The gaining of electron is a positive charge (+) and the losing of an electron is a negative charge (-).
