What is the relationship between the number of elements in each period...
The number of elements in each period is twice the number of atomic orbitals available in the energy level that is being filled.
Let's understand it by taking the elements of the 4th period.
In the fourth period, there are 18 elements. The types of subshells used in the 4th period are s, p, and d.
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
The total number of elements is 18 i.e. twice the total number of orbitals.

Periodic Table and Atomic Orbitals
The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and chemical properties. The periodic table is divided into horizontal rows called periods and vertical columns called groups.
Atomic orbitals are regions of space where electrons are likely to be found in an atom. The electrons in an atom occupy different energy levels or shells. Each energy level is composed of one or more atomic orbitals.
Relationship between the number of elements in each period and the number of atomic orbitals available in the energy level that is being filled
The number of elements in each period of the periodic table is related to the number of atomic orbitals available in the energy level that is being filled. This relationship can be explained as follows:
- In the first period, there is only one energy level (n=1) available for electrons to occupy. This energy level can hold a maximum of 2 electrons, which can occupy only one atomic orbital (1s). Therefore, there are only 2 elements (hydrogen and helium) in the first period of the periodic table.
- In the second period, there are two energy levels (n=1 and n=2) available for electrons to occupy. The first energy level (n=1) can hold a maximum of 2 electrons, which occupy the 1s orbital. The second energy level (n=2) can hold a maximum of 8 electrons, which occupy four atomic orbitals (2s, 2px, 2py, and 2pz). Therefore, there are 8 elements in the second period of the periodic table.
- In the third period, there are three energy levels (n=1, n=2, and n=3) available for electrons to occupy. The first energy level (n=1) can hold a maximum of 2 electrons, which occupy the 1s orbital. The second energy level (n=2) can hold a maximum of 8 electrons, which occupy four atomic orbitals (2s, 2px, 2py, and 2pz). The third energy level (n=3) can hold a maximum of 18 electrons, which occupy nine atomic orbitals (3s, 3px, 3py, 3pz, 3dxy, 3dxz, 3dyz, 3dx2-y2, and 3dz2). Therefore, there are 8+8+2=18 elements in the third period of the periodic table.
From the above explanation, it can be observed that:
- The number of elements in each period of the periodic table is twice the number of atomic orbitals available in the energy level that is being filled.
- Therefore, the correct answer is option 'A'.

What is the relationship between the number of elements in each period...
Each orbital can accomodate 2 electrons and each successive element in a period involves addition of 1 electron so each period can have twice the number elements that of orbital
