Question

In what period and group will an element with Z=118will be present.Explain briefly

Answer 1

See,mate..

Given Z(atomic number) is 118.

After the 100th atomic number..All the other elements' group number can be checked by the formula (Group number = Given atomic number - 100)

So if Z is 101 == Group is 1
Z is 102 == Group is 2

Given Z is 118,So group number is 18.

Now to check for the period We know radon Z=86 is the last noble gas(It lies in the 6th period) And atomic number after it will lie in the 7th period.
