Ionic bond

Types of Bonds: Ionic, Covalent, Metallic.

Ionic bonding is the bonding between a nonmetal and a metal, it occurs when charged atoms attract after one or more electrons is lost. Examples of ionic bonds include sodium chloride or NaCl, as well as magnesium oxide MgO.

Appearance- powdery or grainy.                                     Solubility in water- yes.                                                              Melting point- doesn't melt easily.                                    Conductivity- (solid) no (liquid) yes (dissolved in water) yes.

Covalent bond

Covalent bonding is a chemical bond that involves the sharing of electrons pairs between  atoms. Examples of covalent bonds include water, methane, and carbon dioxide.

Appearance- powdery or grainy.                                         Solubility in water- sometimes yes others no.     Melting point- melts easily.                                               Conductivity- (solid) no (liquid) no (dissolved in water) no.

Metallic bonds

Metallic bonding is the electrostatic  attraction between the positively charged atomic nuclei of metal atoms  and the delocalized metals in the atom. Examples of atomic bonds include copper, zinc, sodium and silver.

Appearance- shiny                                                                                    Solubility in water- no.                                                                                                           Melting point- does not melt easily.                           Conductivity- (solid) yes (liquid) yes (dissolved in water) NA.
