8.6: Metals, Nonmetals, and Metalloids

Nonmetals. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids.

The first member of each nonmetal group exhibits different behaviors, in many respects, from the other group members. The reasons for this include smaller size, greater ionization energy, and (most important) the fact that the first member of each group has only four valence orbitals (one 2s and three 2p) available for bonding, whereas other group …

Metals, Nonmetals, and Metalloids of the Periodic Table

Elements of the periodic table are grouped as metals, metalloids or semimetals, and nonmetals. The metalloids separate the metals and nonmetals on a periodic table. Also, many periodic tables have a stair-step line on the table identifying the element groups. The line begins at boron (B) and extends down to polonium (Po).

Ceramics are prepared by taking mixtures of clay, powders, earthen elements and water. These are shaped into desired forms. After shaping, it is fired in a high temperature oven called kiln. Feldspar is a very important raw material in the manufacture of glass because it acts as a fluxing agent, reducing the melting temperature of quartz.

The Difference Between Metals and Nonmetals

Hydrogen is a good example of an element that acts as a nonmetal some times, but as a metal other times. Under normal conditions, hydrogen is a gas. As such, it acts like a nonmetal. But, under high pressure it becomes a solid metal. Even as a gas, hydrogen often forms the +1 cation (a metallic property).

The modern statement of this relationship, the periodic law, is as follows: the properties of the elements are periodic functions of their atomic numbers.A modern periodic table arranges the elements in increasing order of their …

Characteristics of Nonmetals

Elemental Properties. In the elemental form, non-metals can be gas, liquid or solid. They aren't shiny (lustrous) and they don't conduct heat or electricity well. Usually their melting points are lower than for metals, although there are exceptions. The solids usually break easily, and can't bend like metals.

The stronger a nonmetal is as an oxidizing agent, the more difficult it is to oxidize the anion formed by the nonmetal. This means that the most stable negative ions are formed by elements at the top of the group or in group 17 of the period. Fluorine and oxygen are the strongest oxidizing elements known.
