Carbon is the single most important element to the existence of life on Earth. Nonmetals show more variability in their properties than do metals. Among the non-metals, the anionic dopants have a strong influence on the VB. More on the Elements and the Periodic Table Elements Periodic Table. Nonmetals can form different types of bonds depending on their partner atoms. The following are the physical properties of metal : The physical properties make them useful for many purposes. Metalloids. Non-Metal dopants are carbon, nitrogen, fluorine, sulphur and iodine. Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. Physical State: Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). The nonmetal element group is a subset of these elements. Selenium gets its name from the Greek word "selene" which means "Moon." Different chemical models have different features and limitations. Properties of Non metals. Nonmetals have properties opposite those of the metals. Many nonmetals can gain metallic properties under very high pressures. Properties of metals can be explained in terms of metallic structure and bonding. As their name suggests, nonmetals generally have properties that are very different from the properties of metals. Physical Properties of Nonmetals. Properties of Nonmetals. These properties are largely determined by the interatomic bonding strengths and molecular structures of the nonmetals involved, both of which are subject to variation as the number of valence electrons in each nonmetal varies. Copper is used in making electric wires, gold is used to make jewellery, stainless steel is used to make pots, pans, etc The nonmetals in the periodic table. Ionic Bonds. Nonmetals include the nonmetal group, the halogens, and the noble gases. Only bromine exists as a liquid at room temperature. The nonmetal element group consists of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium. For e.g. The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions. These elements have similar chemical properties that differ from the elements considered metals. Non-Malleable and Ductile: Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets. Because of these properties non-metals usually gain electrons when reacting with other compounds, forming covalent bonds. Characteristics properties of non-metals are high ionization energies and high electronegativity. Properties of nonmetals include a relatively low boiling point, which explains why many of them are gases at room temperature. Physical Properties of Metals. Some nonmetals are liquids. Metals and non-metals have different properties. These elements are shown in the following figure.
