Chlorine, chemical element of the halogen group that is a toxic, corrosive, greenish yellow gas, irritating to the eyes and respiratory system. Melting Point (Freezing Point) The temperature at which solid chlorine melts or liquid … At 0.099%, phosphorus is the most abundant pnictogen in the Earth’s crust. Very soft and malleable, indium has a melting point higher than sodium and gallium, but lower than lithium and tin. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. Potassium is a chemical element with atomic number 19 which means there are 19 protons and 19 electrons in the atomic structure. Europium is one of the least abundant elements in the universe. The chemical symbol for Cadmium is Cd. Commercially, thallium is produced as a byproduct from refining of heavy metal sulfide ores. The chemical symbol for Phosphorus is P. As an element, phosphorus exists in two major forms—white phosphorus and red phosphorus—but because it is highly reactive, phosphorus is never found as a free element on Earth. [It was also known as muriatic acid and we now call it hydrochloric acid.] The melting point of a substance depends on pressure and is usually specified at standard pressure. On the other hand, ice (solid H2O) is a molecular compound whose molecules are held together by hydrogen bonds, which is effectively a strong example of an interaction between two permanent dipoles.

Neptunium metal is silvery and tarnishes when exposed to air. Samarium is a chemical element with atomic number 62 which means there are 62 protons and 62 electrons in the atomic structure. Americium is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas. 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’. Though hydrogen bonds are the strongest of the intermolecular forces, the strength of hydrogen bonds is much less than that of ionic bonds. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. Such weak intermolecular bonds give organic molecular substances, such as waxes and oils, their soft bulk character, and their low melting points (in liquids, molecules must cease most structured or oriented contact with each other). The chemical symbol for Platinum is Pt. Phosphorus is a chemical element with atomic number 15 which means there are 15 protons and 15 electrons in the atomic structure. Another factor affecting the melting point of ionic compounds is the number of charges on the ion. Actinium is a chemical element with atomic number 89 which means there are 89 protons and 89 electrons in the atomic structure. Chlorine dioxide is a chemical compound with the formula ClO 2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between −59 °C and 11 °C, and as bright orange crystals when colder.
