The no of element in each period is twice the numbers of the atomic orbital available in the Energy level that being filled
Answers
Elements are twice the number of the orbitals.
Lets understand it by taking the elements of 4th period. In fourth period there are 18 elements. The types of the subshells used in 4th period are s, p and d so,
Number of orbitals of s subshell = 1
Number of orbitals of p subshell =3
Number of orbitals of d subshell =5
Total number of orbitals = 9
Total number of elements = 18 which is twice the total number of orbitals.
