Answer:

a) atomic number of ELEMENT REFERS to the number of PROTONS present in the nucleus of the cell

b) 1)no. of protons=17 no. of electron=17 no. of nutrons=18 atomic no.=17 mass no.=35

2)no. of protons=17 no. of electron=17 no. of nutrons=20 atomic no.=17 mass no.=37

c)1) electronic configuration of cl=2,7

2)electronic configurations of cl-=2,8
