Answer 1

Answer:

it

is used for mathematics equation

Answer 2

Answer:

n +1 rule : The energy of an electron in a multi-electron atom, depends both on the principal quantum number, n, and the azimuthal quantum number, l. The lower the sum (n +1) for an orbital, the lower is its energy. If two orbitals have the same (n +l) values then orbital with the lower value of n is of lower energy. This is called the (n +1) rule. From the (n +1) rule the increasing order of energy of orbitals in multi-electron atoms can be written as : 1s <2s < 2p < 3 < 3p < 4s <3d < 4p <5s < 4d <5p < 6s <4f < 5d < 6p <7s ..........
