Being a typical member of the lanthanide series, europium usually assumes the oxidation state +3. Heavy nuclei with an even number of protons and an even number of neutrons are (due to Pauli exclusion principle) very stable thanks to the occurrence of âpaired spinâ. Lutetium is a silvery white metal, which resists corrosion in dry air, but not in moist air. Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. What is the time signature of the song Atin Cu Pung Singsing?
Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite.
Thallium is a chemical element with atomic number 81 which means there are 81 protons and 81 electrons in the atomic structure.

The chemical symbol for Lead is Pb. Polonium is a rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth. 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 chemical symbol for Platinum is Pt. Nickel is a silvery-white lustrous metal with a slight golden tinge. Since a stable atom has a net charge of 0, we must have 20 electrons. 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 far more common in the universe as a whole than on Earth. The chemical symbol for Molybdenum is Mo.
Electrical resistance is expressed in Ohms. Ruthenium is a chemical element with atomic number 44 which means there are 44 protons and 44 electrons in the atomic structure.
The chemical symbol for Magnesium is Mg. Magnesium is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. Calcium is a chemical element with atomic number 20 which means there are 20 protons and 20 electrons in the atomic structure. The chemical symbol for Osmium is Os. Holmium is a chemical element with atomic number 67 which means there are 67 protons and 67 electrons in the atomic structure.
Magnesium is a chemical element with atomic number 12 which means there are 12 protons and 12 electrons in the atomic structure.
In nuclear industry gadolinium is commonly used as a neutron absorber due to very high neutron absorbtion cross-section of two isotopes 155Gd and 157Gd. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Chlorine is a chemical element with atomic number 17 which means there are 17 protons and 17 electrons in the atomic structure. Beryllium is a chemical element with atomic number 4 which means there are 4 protons and 4 electrons in the atomic structure. It must be noted, especially nuclear cross-sections may vary by many orders from nuclide with the neutron number N to nuclide with the neutron number N+1.
Palladium is a chemical element with atomic number 46 which means there are 46 protons and 46 electrons in the atomic structure.
