Chemistry

Covalent Bond

Bond formed by mutual sharing of electrons between combining atoms

Electrovalency

Number of electrons which an atoms gains or loses

Electrovalent Bond

Electrostatic force which holds the oppositely charged ions together. Also called as Ionic Bond

Chemical Bond

The attractive forces which holds the particles such as atoms, ions and molecules together

Hund’s Rule

Pairing of electrons in orbitals of same subshell cannot take place until all orbitals have one electron

Pauli’s Exclusion Principle

All the four quantum numbers are not same for electrons in the atom

Aufbau Rule

Orbitals are filled with electrons in the increasing order of energy

Electronic Configuration

Represents the distribution of electrons in various orbitals inside the atom

Spin Quantum Number

Specifies the spin of the electron

Magnetic Quantum Number

Specifies the orientation of the electron in the subshell
