Titanium condenser tubes are usually the best technical choice, however titanium is very expensive material. On the other hand, nuclei with an odd number of protons and neutrons are mostly unstable. Thorium is moderately hard, malleable, and has a high melting point. Explanation:Atomic number represents the total number of protons present in an atom. Although classified as a rare earth element, samarium is the 40th most abundant element in the Earth’s crust and is more common than such metals as tin. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.    Boiling Point  Comments For 12C the atomic mass is exactly 12u, since the atomic mass unit is defined from it.

Question.    Alkali Metals It is one of the least reactive chemical elements and is solid under standard conditions. Uranium is a silvery-white metal in the actinide series of the periodic table. Be it physics or chemistry, students of elementary science need to be aware of the ways on how to find protons, neutrons, and electrons. Its extreme rarity in the Earth’s crust, comparable to that of platinum. For other isotopes, the isotopic mass usually differs and is usually within 0.1 u of the mass number. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) stabilizes the free metal somewhat against further oxidation. Silicon is a hard and brittle crystalline solid with a blue-grey metallic lustre, it is a tetravalent metalloid and semiconductor. The chemical symbol for Mercury is Hg.
