Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Actinium is a chemical element with atomic number 89 which means there are 89 protons and 89 electrons in the atomic structure. Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite. Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Covalent bonds often result in the formation of small collections of better-connected atoms called molecules, which in solids and liquids are bound to other molecules by forces that are often much weaker than the covalent bonds that hold the molecules internally together. Chemically, sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases. Naturally occurring potassium is composed of three isotopes, of which 40K is radioactive. Thulium is an easily workable metal with a bright silvery-gray luster. The name xenon for this gas comes from the Greek word ξένον [xenon], neuter singular form of ξένος [xenos], meaning ‘foreign(er)’, ‘strange(r)’, or ‘guest’. Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. Carbon is one of the few elements known since antiquity. Why is the Formula for Bromine Br2 in a Liquid State and not Br? Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices. Commercially, thallium is produced as a byproduct from refining of heavy metal sulfide ores. In nuclear industry cadmium is commonly used as a thermal neutron absorber due to very high neutron absorption cross-section of 113Cd. Discoverer: Scientists at Dubna, Russia (1964)/Albert Ghiorso et. Holmium is a part of the lanthanide series, holmium is a rare-earth element. The chemical symbol for Strontium is Sr. Strontium is an alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly reactive chemically. It is a noble metal and a member of the platinum group. Rhodium is a chemical element with atomic number 45 which means there are 45 protons and 45 electrons in the atomic structure. These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). The chemical symbol for Ruthenium is Ru. It occurs on Earth as the decay product of various heavier elements. Organic bromines, however, can also cause damage to organs such as the liver, kidneys, lungs, and can cause stomach and gastrointestinal malfunctions. It is also sometimes considered the first element of the 6th-period transition metals and is traditionally counted among the rare earth elements. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. Note that, these points are associated with the standard atmospheric pressure. Zirconium is widely used as a cladding for nuclear reactor fuels. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. It is a dense and reddish-brown compound that evaporates quickly at room temperature to a red vapor with a strong, chlorine-like odor. Bromine compound is a molecule formed when two bromine atoms combine together. Bromine is very poisonous to humans as it can cause painful burns when contacted with human skin. Bromine is used as an emulsifier in various citrus-flavored soft drinks. Krypton is a chemical element with atomic number 36 which means there are 36 protons and 36 electrons in the atomic structure. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl. Pure bromine is always diatomic. Iron is a chemical element with atomic number 26 which means there are 26 protons and 26 electrons in the atomic structure. Thorium is commonly found in monazite sands (rare earth metals containing phosphate mineral). It is sold like salts or other compounds because the pure bromine is expensive and challenging to produce. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine. The chemical symbol for Helium is He. The chemical symbol for Rubidium is Rb. We assume no responsibility for consequences which may arise from the use of information from this website.

Used in gold mining extraction processes and in oil- and gas-well drilling. The chemical symbol for Rhenium is Re. Bromine has various physical properties. Boron is a chemical element with atomic number 5 which means there are 5 protons and 5 electrons in the atomic structure.
