is bohrium a metal or nonmetal?
314304
In the periodic table, it is a d-block transactinide element. It is a member of the 7th period and belongs to the group 7 elements as the fifth member of the 6d series of transition metals. Chemistry experiments have confirmed that bohrium behaves as the heavier homologue to rhenium in group 7.

Metalloids have properties in between those of the metals and non-metals and are semiconductors (whereas metals are conductors and nonmetals are not conductors) and used extensively in circuitry (like computer chips). ... They can be shiny (have luster) or not whereas all metal are shiny.

Transition metals are essentially metallic elements. ... On the other hand, metalloids are not metal or nonmetals. However, they have chemical and physical properties that lie between metals and nonmetals.

Boron is a non metallic element and the only non-metal of the group 13 of the periodic table the elements. Boron is electron-deficient, possessing a vacant p-orbital. It has several forms, the most common of which is amorphous boron, a dark powder, unreactive to oxygen, water, acids and alkalis.

The chemical element krypton is classed as a noble gas and a nonmetal.

Elements are typically classified as either a metal or nonmetal, but the dividing line between the two is fuzzy. Metal elements are usually good conductors of electricity and heat. The subgroups within the metals are based on the similar characteristics and chemical properties of these collections.

Discovery: Bohrium was first discovered by a team of scientists in Dubna, Russia, in 1976. The discovery was confirmed by Peter Armbruster, Gottfried Münzenber and their team working in Darmstadt, Germany, in 1981. There are 10 isotopes of bohrium with known half-lives.

Bohrium's most stable isotope, bohrium-270, has a half-life of about 1 minute. It decays into dubnium-266 through alpha decay. Since only a few atoms of bohrium have ever been made, there are currently no uses for bohrium outside of basic scientific research.

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.

Boron. Boron is a non metallic element and the only non-metal of the group 13 of the periodic table the elements. Boron is electron-deficient, possessing a vacant p-orbital. It has several forms, the most common of which is amorphous boron, a dark powder, unreactive to oxygen, water, acids and alkalis.

Metals tend to be strong and conductive, and have high melting points. However, like nonmetals, their forms occur as a distinct combination of electrons, protons and neutrons. All elements, metal or otherwise, can change state or react.

A nonmetal is typically brittle when solid and usually has poor thermal conductivity and electrical conductivity. Chemically, nonmetals tend to have relatively high ionization energy, electron affinity, and electronegativity. They gain or share electrons when they react with other elements and chemical compounds.

Unlike metals, non-metals are poor conductors of heat and electricity. They are brittle and usually dull in color. They sound boring, but they're actually the coolest. Carbon (C, Z = 6) is one of the least boring elements on the periodic table.

Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common. They are: dull (not shiny)

Non-Ferrous Metals. Nonferrous metals offer a wide variety of mechanical properties and material characteristics. Nonferrous metals are specified for structural applications requiring reduced weight, higher strength, nonmagnetic properties, higher melting points, or resistance to chemical and atmospheric corrosion.
