Question

In the modern periodic table, the number of period of the element is the same as 1) principal quantum number 2) atomic number 3)azimuthal quantum number 4)atomic mass (pls ans only if u know)

Answer 1

option a principal quantam number

Answer 2

The principal quantum number 'n' is the same as the number of period of the element In the modern periodic table.(option - 1)

• A period tells the value of n for the outermost shells of the element placed in front of that period.
• There are four types of quantum numbers:-
• Azimuthal quantum number- number of subshells present in the main orbital.
• the magnetic quantum number gives the spin of electrons.
• angular momentum number - l- the type of orbital in which an electron is present.
