Chemical Bonding

ionic bond

A type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically involving the transfer of electrons from one atom to another.

Which bond is non-directional in nature

ionic

no. of charges carried by anion or cation during formation of ionic bond

electrovalency

Variable electrovalency causes

unstable nature of core
inert e- pair effect

Factor for ionic - gain/ ion enthalpy

low (cation/anion form)

Latice energy

energy released when ions bond in a crystal lattice of one gram mole of an ionic compound

ionic properties

hard
high melting boiling points
water soluble
electrical conductivity in molten/aq
no stereoisomerism

covalent properties

soft
usually low melting boiling points
often insoluble in water
poor electrical conductivity

Formal charge

diff bw e- in free state and lewis structure

bond energy Cl2, F2, Br2, I2

Cl2>Br2>F2>I2

Which is more effective in forming bonds, hybrid or pure orbitals

Hybrid coz they allow for better overlap with the atomic orbitals of other atoms
