What is chemical bonding and mole concept meaning

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

The mole is the unit of measurement for amount of substance in the International System of Units. It is defined as exactly 6.02214076×10²³ constitutive particles, which may be atoms, molecules, ions, or electrons.

remembering this number is really important but u can also just put 6.02×10²³ instead, it would still be the same.
