Chemical bonding is a mutual electrical attraction between the nuclei and valence electrons of different atoms that bind atoms together.
There are three types of chemical bonds: ionic, covalent, metallic
An ionic bond is a chemical bond that results from the electrical attraction between cations and anions.
1) dissolve in water
2) does not melt
3) conductivity: solid-no, liquid-yes, dissolved-yes
A covalent bond results from sharing of electron pairs between two atoms.
1) dissolves in water
2) low melting point
3) never conducts electricity
4) shares electrons
A metallic bond is the electrostatic attraction between the positively charged atomic nuclei of metal atoms and the delocalised electrons in the metal.
2) not soluble
3) high melting point
4) always conducts electricity
