#ELECTRON CONFIGURATION FOR ANTIMONY FREE#

However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. It must be noted, atoms lack a well-defined outer boundary. The atomic radius of Antimony atom is 139pm (covalent radius). Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Mass numbers of typical isotopes of Antimony are 121, 123. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Chemical Properties of Antimony Atomic number, 51, Relative atomic mass, 121.76 State at 20C, Solid, Key isotopes Sb Electron configuration. Oxidation states: +3,5/-3 Major edges What are these symbols K 30491. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.įor stable elements, there is usually a variety of stable isotopes. Electron configuration: Kr4d 10 5s 2 5p 3. Neutron number plus atomic number equals atomic mass number: N+Z=A. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10 -19 coulombs. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Electron configuration of Antimony is Kr 4d10 5s2 5p3. In the periodic table, the elements are listed in order of increasing atomic number Z. Atomic Number – Protons, Electrons and Neutrons in AntimonyĪntimony is a chemical element with atomic number 51 which means there are 51 protons in its nucleus. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior.
