If spins of electrons is assumed to be 3 [three values] then no of elements are placed in \(3^{rd }\) period

If spins of "e" assumed to be 3 three values then no of elements are placed in 3^(rd) period

The group 18 element placed in period 3

The maximum number of elements in 3^(rd) period is :

If each orbital can take maximum of three electrons, the number of elements in the third period of the periodic table will be:

(a) What is the main characteristic of the last elements in the periodic of the periodic table? What is the general name of such elements? (b) What is he number of elements in : (a) 1st period, and (b) 3rd period, of the modern periodic table?

It each orbital can hold a maximum of three electrons, the number of elements in 9th period of periodic table (long form) are:

If spin quantum number has 4 possible values. S=+1,-1,+(1)/(2),-(1)/(2) then how many elements are possible in 3rd period. [Divide your answer by 2]
