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 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 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.
