Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin. Pure germanium is a semiconductor with an appearance similar to elemental silicon.

Solid state electronics arises from the unique properties of silicon and germanium, each of which has four valence electrons and which form crystal lattices in which substituted atoms (dopants) can dramatically change the electrical properties.

33 electrons

Explanation: As is the chemical symbol for the element arsenic. In a neutral atom, the number of electrons equals the number of protons, which means that neutral arsenic atoms have 33 electrons.

The most common is metallic gray, followed by yellow and then black. Gray arsenic, the only form used in industry, is the most stable of the three and the strongest conductor of electricity.

Ta

Tantalum is a grey, heavy and hard metal with high corrosion resistance and the highest known ability of all metals to store electricity. It is very rare, averaging 2 ppm in the earth’s crust, and is remarkable for its unsurpassed performance in the diverse end uses that it serves.

Rhodium

Period 4 includes the biologically essential elements potassium and calcium, and is the first period in the d-block with the lighter transition metals. Completing the fourth period are the post-transition metals zinc and gallium, the metalloids germanium and arsenic, and the nonmetals selenium, bromine, and krypton.

Tantalum (Ta), Osmium (Os), and Rhodium (Rh) are all transition metals as they are located at the center of the periodic table….Are you a chemical element?

The signs Ta, Os and Rh stand for metals on the periodic table. Tantalum (Ta), Osmium (Os), and Rhodium (Rh) are all transition metals as they are located at the center of the periodic table. Non-metals are the substances which gain electrons to gain stability and hence they form anions.

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….Metals, Metalloids, and Nonmetals.

metals

Tantalum (Ta), Osmium (Os) and Rhodium (Rh) are metals. Explanation: Metals are good conductors of heat and electricity and they can be hammered into sheets (malleable). Mainly most of them are solids.

Osmium (Os), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table and the densest naturally occurring element.
