Answer

Answer:

  1. Chemical symbol: Li; Atomic number: 3; Element name: Lithium; Atomic mass: 6.94 (approximate value from periodic - table, common value used is 7 for simplicity in some cases)
  2. (a) c. Boron
Element Atomic Number Mass Number Protons Neutrons Electrons
Li 3 7 3 4 3
P 15 31 15 16 15
Cl 17 35 17 18 17
Ni 28 59 (approximate) 28 31 28
K 19 39 19 20 19
Hg 80 201 80 121 80
