Percentage =( Part / Total )×100
A percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol %. For example, 50% means 50 out of 100.
Quantum numbers are crucial because they provide a unique address for each electron in an atom, defining its energy, position, and behavior. They help predict and explain the arrangement of electrons in atoms and the resulting chemical properties.
The spin quantum number (ms) describes the intrinsic spin of the electron within an orbital. It can have one of two values: +1/2 (spin up) or -1/2 (spin down).
The magnetic quantum number (ml) describes the orientation of an orbital in space relative to the other orbitals. Its values range from -l to +l. For instance, if l=1, ml can be -1, 0, or 1.
The azimuthal quantum number (l), also known as the angular or orbital quantum number, defines the subshell and shape of the orbital. It ranges from 0 to n-1. For example, for n=3, l can be 0, 1, or 2.
The principal quantum number (n) indicates the main energy level or shell of an electron within an atom. It can be any positive integer (1, 2, 3,…).
There are four quantum numbers:
- Principal quantum number (n)
- Azimuthal quantum number (l)
- Magnetic quantum number (ml)
- Spin quantum number (ms)
Quantum numbers are a set of values that describe the position and energy of an electron in an atom. They define the properties of atomic orbitals and the electrons in those orbitals.
