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

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

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

The group 18 element placed in period 3

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]

(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?

An element 'E' has atomic number 14. To which period this element belongs? How many number of elements are present in the period to which element ' E' belongs?

Give the names of the first three elements of the periodic table.

What is the value of (n+l) for the unpaired e^(-) in an atom of an element which is present in the 3rd period and seventeenth group of the periodic table.
