A = 35
N = 18
P = A-N = 35-18 = 17
=> Z = 17
Name of element is Chlorine (Cl)
E.C. = K L M
2 8 7
Valency = -1
Group No. = 17
Period = 3
Hope that the other information helps you.

heyaaaaa.....
heres ur ans......
atomic mass = no of protons + no of neutrons
=>35= 18+ no of proton
=>no of proton= 35-18=17
atomic no =17
electronic configuration = 2,8,7
grp no.= 17
period = 3
valency= 1
hope this helps
brainliest plzzz
