Metalloid - Wikipedia

A metalloid is a type of chemical element which has properties in between, or that are a mixture of, those of metals and nonmetals.There is neither a standard definition of a metalloid nor complete agreement on the elements appropriately classified as such. Despite the lack of specificity, the term remains in use in the literature of chemistry.. The six commonly recognised metalloids are boron ...

Melting Points of Metals vs. Nonmetals | Sciencing

Mercury, the metal with the lowest melting point -- -38.9 degrees Celsius or -37.9 degrees Fahrenheit -- cannot form any bonds since it has zero electron affinity. A lot of nonmetals, like oxygen and chlorine are highly electronegative: they have high affinity for electrons and effectively pry them from the other atom, so the bond breaks easily.

The Difference Between Metals and Nonmetals

Elements may be classified as either metals or nonmetals based on their properties. Much of the time, you can tell an element is a metal simply by looking at its metallic luster, but this isn't the only distinction between these two general groups of elements.

Elements (NonMetals)

Nonmetals 2 Boron B Of group 13 elements only Boron is a nonmetal Boron B3+ - never formed because it requires too much energy to remove the three electrons and energy cannot be supplied by the lattice energy Boron does not occur free in nature but found in a variety of different ores

Types of Bonds | Introduction to Chemistry

Nonmetals can form different types of bonds depending on their partner atoms. Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
