Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. Nickel belongs to the transition metals and is hard and ductile. Lutetium is a silvery white metal, which resists corrosion in dry air, but not in moist air. Sodium is a soft, silvery-white, highly reactive metal.
All of its isotopes are radioactive. Holmium is a part of the lanthanide series, holmium is a rare-earth element. The first alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC. The size and mass of atoms are so small that the use of normal measuring units, while possible, is often inconvenient. Mass was no longer considered unchangeable in the closed system.

Naturally occurring potassium is composed of three isotopes, of which 40K is radioactive. Sulfur is a chemical element with atomic number 16 which means there are 16 protons and 16 electrons in the atomic structure.
Lawrencium is the final member of the actinide series. It may seem, that the space and in fact the matter isÂ empty,Â but it is not. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. ForÂ 12C the atomic mass is exactly 12u, since the atomic mass unit is defined from it. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Bismuth is a chemical element with atomic number 83 which means there are 83 protons and 83 electrons in the atomic structure. Neodymium is a soft silvery metal that tarnishes in air.

Significant concentrations of boron occur on the Earth in compounds known as the borate minerals. Caesium has physical and chemical properties similar to those of rubidium and potassium. Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles. The chemical symbol for Barium is Ba. The chemical symbol for Yttrium is Y. Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a ârare-earth elementâ. Mercury is commonly known as quicksilver and was formerly named hydrargyrum. The chemical symbol for Iron is Fe. It is the fifth most abundant element in Earthâs crust and the third most abundant metal, after iron and aluminium. Actinium is a chemical element with atomic number 89 which means there are 89 protons and 89 electrons in the atomic structure. The classical description cannot be used to describe things on the atomic scale. 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.
