ORBIT / SHELL:
Do you Know !!
What is a shell?
Shell is a well-defined circular path in which electron revolves around the nucleus of an atom.
Shell is also known as orbit or energy level .
Atomic Shell is denoted by n.
where n=1 represent the 1st shell ,denoted by K
n=2 represent the 2nd shell ,denoted by L
n=3 represent the 3rd shell ,denoted by M and so on….
Maximum no. of electrons in atomic shells (n) are as follow:
M-shell=18 e- and so on….
Formula to calculate maximum number of electrons in atomic shells:
MAX. NO OF ELECTRONS IN A SHELL= 2n 2
What is meant by sub-shell?
A subshell is a sub division of atomic shells(orbit) separated by electron orbitals.
Subshell also known as sub orbit or sub energy level.
Sub shells are denoted by:
It is a three dimensional probability space (along x y and z-axis)around the nucleus of an atom where the possibility of finding the electron cloud is maximum (95%).
