What do Be and Mg have in common in the periodic table?

Answer 1

Boron and germanium are both metalloid.

Answer 2

A metalloid is a chemical element with properties that are in between or a mixture of those of metals and nonmetals, and which is considered to be difficult to classify unambiguously as either a metal or a nonmetal. There is no standard definition of a metalloid nor is there agreement as to which elements are appropriately classified as such. Despite this lack of specificity the term continues to be used in the chemistry literature.

Physically, metalloids usually have a metallic appearance but they are brittle and only fair conductors of electricity; chemically, they mostly behave as (weak) nonmetals. They can, however, form alloys with metals. Ordinarily, most of the other physical and chemical properties of metalloids are intermediate in nature.

The six elements commonly recognised as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. Being too brittle to have any structural uses, metalloids and their compounds instead find common use in glasses, alloys and semiconductors. The electrical properties of silicon and germanium, in particular, enabled the establishment of the semiconductor industry in the 1950s and the development of solid-state electronics from the early 1960s onward.[

All six elements have toxic and medicinal properties to varying degrees.

Other elements less commonly recognised as metalloids include carbon, aluminium, selenium, polonium and astatine. On a standard Periodic Table these elements, as well as the elements commonly recognised as metalloids, occur in or near a diagonal region of the p-block, having its main axis anchored by boron at one end and astatine at the other. Some periodic tables include a dividing line between metals and nonmetals and it is generally the elements adjacent to this line or, less frequently, one or more of the elements adjacent to those elements, which are identified as metalloids.

The term metalloid was first popularly used to refer to nonmetals. Its more recent meaning as a category of elements with intermediate or hybrid properties did not become widespread until the period 1940–1960. Metalloids are sometimes called semimetals, a practice which has been discouraged. This is because the term semimetal has a different meaning in physics, one that more specifically refers to the electronic band structure of a substance rather than the overall classification of a chemical element.
