Berkelium is a member of the actinide and transuranium element series. The chemical symbol for Einsteinium is Es. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226. They all have 92 protons, of course, but differ in the number of neutrons. Number of neutrons =54 Mass number - Atomic number 114Cd:56 48 119Sn:69 50 Co:32 27 59 59 Ni:31 28 133Cs 78: 55 132 Xe:78 54 Cu34 29 63 Cu:36 29 65 25. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. The number of protons and electrons will be the same. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water. Radon occurs naturally as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into lead. Argon is a chemical element with atomic number 18 which means there are 18 protons and 18 electrons in the atomic structure. Look at the periodic table to find the mass number and atomic number of the elements and using the formula above you can calculate nutrons. Number of isotopes (atoms of the same element wit… Lead is soft and malleable, and has a relatively low melting point. 5H is another highly unstable heavy isotope of hydrogen. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. Mercury is commonly known as quicksilver and was formerly named hydrargyrum. Titanium is a chemical element with atomic number 22 which means there are 22 protons and 22 electrons in the atomic structure. Neutrons. The chemical symbol for Cobalt is Co. Cobalt is found in the Earth’s crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The chemical symbol for Polonium is Po. Isotopes are created when you change the normal number of neutrons in an atom. Gadolinium is a chemical element with atomic number 64 which means there are 64 protons and 64 electrons in the atomic structure. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent for its strong resistance to corrosion. It comprises 1 proton and 3 neutrons in its nucleus. Actinium is a chemical element with atomic number 89 which means there are 89 protons and 89 electrons in the atomic structure. The chemical symbol for Potassium is K. Potassium was first isolated from potash, the ashes of plants, from which its name derives. Silicon is a chemical element with atomic number 14 which means there are 14 protons and 14 electrons in the atomic structure. Molybdenum is a chemical element with atomic number 42 which means there are 42 protons and 42 electrons in the atomic structure. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths. 1) You may use almost everything for non-commercial and educational use. The chemical symbol for Neodymium is Nd. Hydrogen-4.1. Atomic symbol (on the Periodic Table of Elements): H 3. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. The first two of these are stable, while 3H has a half-life of 12.32 years. The chemical symbol for Selenium is Se. Lead is widely used as a gamma shield. Number of neutrons=1-1=0. The chemical symbol for Fermium is Fm. All heavier isotopes are synthetic and have a half-life less than a zeptosecond (10-21 sec). It has a natural abundance … Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. Francium is a highly radioactive metal that decays into astatine, radium, and radon. Plutonium is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. There are also heavier isotopes, which are all synthetic and have a half-life less than one zeptosecond (10−21 second). Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite. For most of the 16 lightest elements (up to oxygen) the number of neutrons is equal to the number of protons. 4H contains one proton and three neutrons in its nucleus. For helium, it is 4: two protons and two neutrons. It is the heaviest essential mineral nutrient. Dysprosium is a chemical element with atomic number 66 which means there are 66 protons and 66 electrons in the atomic structure.
