Like all elements with atomic number over 100, nobelium can only be produced in particle accelerators by bombarding lighter elements with charged particles. The chemical symbol for Manganese is Mn. Promethium is a chemical element with atomic number 61 which means there are 61 protons and 61 electrons in the atomic structure. Nearly all technetium is produced synthetically, and only minute amounts are found in the Earth’s crust. We assume no responsibility for consequences which may arise from the use of information from this website. The temperature at which the phase transition occurs is the melting point. It is even less abundant than the so-called rare earths. Its properties are thus intermediate between those of chlorine and iodine. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. Brinell hardness:   440-600 MPa Samarium is a chemical element with atomic number 62 which means there are 62 protons and 62 electrons in the atomic structure.

Astatine is the rarest naturally occurring element on the Earth’s crust. It is also sometimes considered the first element of the 6th-period transition metals and is traditionally counted among the rare earth elements. The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers.
