An element ''X'' has mass number 35 and number of neutrons is 18. Identify group number and period of the element ''X''.

Text Solution

Verified by Experts

Mass Number = Protons + Neutrons
Number of protons = 17, therefore Atomic number of .X. = 17 Hence .X. belongs to `3^(rd)` period and `17^(th)` group.
