potassium atomic number

Natural boron consists primarily of two stable isotopes, 11B (80.1%) and 10B (19.9%). Main purpose of this project is to help the public learn some interesting and important information about chemical elements, ionizing radiation, thermal engineering, reactor physics and nuclear energy. Lead is a heavy metal that is denser than most common materials. The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis. Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. Atomic Weight = 39.0983. Platinum is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. It occurs naturally in seawater and in many minerals. Erbium is a silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. The chemical symbol for Calcium is Ca. The chemical symbol for Sulfur is S. Sulfur is abundant, multivalent, and nonmetallic. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine. The chemical symbol for Ytterbium is Yb. It is an Alkali Metal and is located in Group 1 of the periodic table. Selenium is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. Yttrium is a chemical element with atomic number 39 which means there are 39 protons and 39 electrons in the atomic structure. Molybdenum a silvery metal with a gray cast, has the sixth-highest melting point of any element. Because of its high chemical reactivity, barium is never found in nature as a free element. In the periodic table, potassium is one of the alkali metals. Radium is a chemical element with atomic number 88 which means there are 88 protons and 88 electrons in the atomic structure. Thorium is a naturally-occurring element and it is estimated to be about three times more abundant than uranium. Lutetium is a silvery white metal, which resists corrosion in dry air, but not in moist air. The chemical symbol for Samarium is Sm. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars. Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Trivial name of Potassium is alkali metals*. Thulium is the thirteenth and third-last element in the lanthanide series. The chemical symbol for Phosphorus is P. As an element, phosphorus exists in two major forms—white phosphorus and red phosphorus—but because it is highly reactive, phosphorus is never found as a free element on Earth. An alloy of sodium and potassium (NaK) is used as a heat-transfer medium. Potassium is a chemical element with atomic number 19 which means there are 19 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Potassium, found in most soils, is an element that is … Potassium atoms have 19 electrons and the shell structure is 2.8.8.1. Neptunium metal is silvery and tarnishes when exposed to air. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. Ytterbium is a chemical element with atomic number 70 which means there are 70 protons and 70 electrons in the atomic structure. The bulk properties of astatine are not known with any certainty. The chemical symbol for Terbium is Tb. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. Rhenium is a silvery-white, heavy, third-row transition metal in group 7 of the periodic table. Lithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure. Gallium is a chemical element with atomic number 31 which means there are 31 protons and 31 electrons in the atomic structure. The chemical symbol for Gadolinium is Gd. Mercury is commonly known as quicksilver and was formerly named hydrargyrum. It rarely occurs in its elemental state or as pure ore compounds in the Earth’s crust. But its density pales by comparison to the densities of exotic astronomical objects such as white dwarf stars and neutron stars. Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. The chemical symbol for Dysprosium is Dy. This page was created by Yinon Bentor.
