Types of Elements

1. Metals

1.1. examples are Iron, Magnesium, Cobalt

1.2. Chemically, the precious metals are less reactive than most elements, have high luster and high electrical conductivity.

2. Metalloids

2.1. examples are Antimony, Arsenic, Tellurium

2.2. any chemical element which has properties in between those of metals and nonmetals, or that has a mixture of them.

3. non- Metals

3.1. chemical element that mostly lacks metallic attributes. Physically, nonmetals tend to be highly volatile (easily vaporized), have low elasticity, and are good insulators of heat and electricity; chemically, they tend to have high ionization energy and electronegativity values, and gain or share electrons when they react with other elements or compounds.

3.2. examples are Oxygen, Hydrogen, Helium
