Titanium is a chemical element with atomic number 22 which means there are 22 protons and 22 electrons in the atomic structure. Cerium is the second element in the lanthanide series. Nearly all technetium is produced synthetically, and only minute amounts are found in the Earth’s crust. Although classified as a rare earth element, samarium is the 40th most abundant element in the Earth’s crust and is more common than such metals as tin. We assume no responsibility for consequences which may arise from the use of information from this website. The chemical symbol for Helium is He. The chemical symbol for Chromium is Cr. The chemical symbol for Lutetium is Lu. The chemical symbol for Francium is Fr. It is a semiconductor. These all are stable isotopes. Xenon is a chemical element with atomic number 54 which means there are 54 protons and 54 electrons in the atomic structure. It has 27 synthetic isotopes which have high nuclear energy and are unstable. It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. Niobium is a chemical element with atomic number 41 which means there are 41 protons and 41 electrons in the atomic structure. This fact has key implications for the building up of the periodic table of elements. Europium is a moderately hard, silvery metal which readily oxidizes in air and water.

The chemical symbol for Germanium is Ge.

This ends our coverage on the topic “Germanium”. The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. Nobelium is the tenth transuranic element and is the penultimate member of the actinide series. The chemical symbol for Aluminum is Al.

Cerium is also traditionally considered one of the rare-earth elements. Pro, Vedantu Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. An atom of an element in a compound will have a positive oxidation state if it has had electrons removed. The chemical symbol for Neptunium is Np.

It is mined from various ores such as sphalerite etc. The chemical symbol for Actinium is Ac. It has 5 natural isotopes which are 70Ge, 72Ge, 73Ge, 74Ge and 76Ge. hot H2SO4 and HNO3 slowly, but it reacts very violently with molten base. Rhenium is a silvery-white, heavy, third-row transition metal in group 7 of the periodic table. Krypton is a member of group 18 (noble gases) elements. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure.
