35-18=17 atomic number
EC of 17- 2,8,7
Period 3 Group 17

given: mass number is 35 and number of neutrons is 18
to find: group number and period of x
here, number of electrons = mass number-the number of neutrons
hence number of electrons = 35 - 18
that is 17
therefore its electronic configuration is 2,8,7 hence we can see that the required element is Chlorine (Cl) which means that it is present in group 17 and period 3
