The boiling point of hassium is not known. Very soft and malleable, indium has a melting point higher than sodium and gallium, but lower than lithium and tin. It rarely occurs in its elemental state or as pure ore compounds in the Earth’s crust.Bromine is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. There are over 100 different borate minerals, but the most common are: borax, kernite, ulexite etc. Mercury is a heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure.Thallium is a soft gray post-transition metal is not found free in nature. Like all elements with atomic number over 100, nobelium can only be produced in particle accelerators by bombarding lighter elements with charged particles.Lawrencium is the final member of the actinide series. It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype. It is the heaviest essential mineral nutrient.Xenon is a colorless, dense, odorless noble gas found in the Earth’s atmosphere in trace amounts. It is by mass the most common element on Earth, forming much of Earth’s outer and inner core. The most commonly used spontaneous fission neutron source is the radioactive isotope californium-252.Einsteinium is the seventh transuranic element, and an actinide.Fermium is a member of the actinide series. Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications.Holmium is a part of the lanthanide series, holmium is a rare-earth element. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air.Strontium is an alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly reactive chemically.Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”.Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite.Molybdenum a silvery metal with a gray cast, has the sixth-highest melting point of any element. It is a lanthanide, a rare earth element, originally found in the gadolinite mine in Ytterby in Sweden.Thulium is an easily workable metal with a bright silvery-gray luster. Major advantage of lead shield is in its compactness due to its higher density. Nearly all technetium is produced synthetically, and only minute amounts are found in the Earth’s crust. Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.Tellurium is a brittle, mildly toxic, rare, silver-white metalloid. Holmium is a relatively soft and malleable silvery-white metal.Erbium is a silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements.

Natural boron consists primarily of two stable isotopes, 11B (80.1%) and 10B (19.9%). al. All of its isotopes are radioactive. Under standard conditions, it is the lightest metal and the lightest solid element. The metal is found in the Earth’s crust in the pure, free elemental form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.Cadmium is a soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins.In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.Gallium has similarities to the other metals of the group, aluminium, indium, and thallium.
