What elements are both metals and nonmetals?

What elements are both metals and nonmetals?

Key Concepts and Summary The elements boron, silicon, germanium, arsenic, antimony, and tellurium separate the metals from the nonmetals in the periodic table. These elements, called metalloids or sometimes semimetals, exhibit properties characteristic of both metals and nonmetals.

Which groups are metals and nonmetals?

Metals, Nonmetals, and Semimetals. The heavy orange zigzag line running diagonally from the upper left to the lower right through groups 13–16 in Figure 2.5. 1 divides the elements into metals (in blue, below and to the left of the line) and nonmetals (in bronze, above and to the right of the line).

What do you call the elements that are between metals and nonmetals?

A metalloid is an element that has properties that are intermediate between those of metals and nonmetals. Metalloids can also be called semimetals.

How do you classify elements as metals or nonmetals?

Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals.

What is Group 6A on the periodic table?

Group 6A (or VIA) of the periodic table are the chalcogens: the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po).

What group are nonmetals?

The nonmetal element group consists of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur and selenium. Hydrogen acts as a nonmetal at normal temperatures and pressure and is generally accepted to be part of the nonmetal group. The halogens are nonmetals in group 7 of the periodic table.

What has similar properties to metals and nonmetals?

Metalloids sit in between the two classifications and share some properties with metals, although they lack the classification of a proper metal. While at room temperature, metalloids have poor conductivity. However, when heated, they become relatively good conductors.

How do you classify metals and nonmetals?

The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids. When elements combine to form compounds, there are two major types of bonding that can result.

What metal is grouped with metalloids?

The post-transition metals cluster to the lower left of this line. Metalloids: The metalloids are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te) and polonium (Po). They form the staircase that represents the gradual transition from metals to nonmetals.
