The atom is the smallest fundamental unit retaining all the properties of an element. It consists of three primary subatomic particles: electrons, protons and neutrons. One type of atom is called a nuclide, characterized by a chemical element symbol, atomic number and mass number. The atomic number represents the number of protons while the mass number denotes the sum of the protons and neutrons in an atom. In the periodic table, the elements are arranged in increasing order based on the atomic number. Several forms of an element may exist, known as isotopes. The different isotopes of an element contain the same number of protons but varying numbers of neutrons.
Nickel is a transition metallic element with the chemical symbol Ni. It is silvery-white in color and highly resistant to corrosion. Nickel is primarily found in metallic iron/nickel sulfides and metallic meteorites, one of which landed in Canada and is the source of around 15 percent of global nickel production.
The most prevalent isotope of nickel has an atomic number of 28 and mass number of 58. Other isotopes of nickel include 60Ni, 61Ni, 62Ni and 64Ni. The number of neutrons for each isotope is 32, 33, 34 and 36, respectively.Learn more about Atoms & Molecules
The element sodium has 12 neutrons. The element also has an atomic number of 11, meaning that it has 11 electrons and 11 protons. It has an atomic mass of 22.9, which is often rounded up to 23 to accurately determine the number of neutrons in the element.Full Answer >
Potassium has 20 neutrons, 19 protons and 19 electrons. It has the chemical symbol K and is an alkali metal. It has a low density of 0.89 grams per cubic centimeter and an atomic weight of 39.09 grams per mole.Full Answer >
Arsenic has 42 neutrons. This gives it an atomic weight of around 75, which is determined by adding the 42 neutrons to arsenic's 33 protons. Arsenic is a poisonous gray solid.Full Answer >
