The charge on an atom is related to its valence electrons or oxidation state. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. In a neutral atom there are as many electrons as protons moving about nucleus. Determine the numbers of protons, neutrons, and electrons in one of these iodine anions. The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Iodine is a bluish-black, lustrous solid. However, other charges are possible. Since it can have more than 8 electrons for its outermost shell (really crazy stuff about atomic orbitals! Iodine: description Your user agent does not support the HTML5 Audio element. It volatilises at ambient temperatures into a pretty blue-violet gas with an irritating odour. Determine the numbers of protons, neutrons, and electrons in one of these iodine anions. ), It can possess many charges. Solution . The most common charges are based on maximum stability for the atom. An atom of an element is most stable when its outer electron shell is completely filled or half-filled. The iodine atoms are added as anions, and each has a 1− charge and a mass number of 127. The ground state electronic configuration of neutral iodine is [Kr].4d 10.5s 2.5p 5 and the term symbol of iodine is 2 P 3/2. The chemical symbol for Iodine is ... Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. For example, hydrogen sometimes has a charge of zero or (less commonly) -1. It gains electrons in order to attain the configuration of a noble gas, which means it gains 3 electrons. Solution The atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Write and interpret symbols that depict the atomic number, mass number, and charge of an atom or ion ; Define the atomic mass unit and average atomic mass; Calculate average atomic mass and isotopic abundance; The development of modern atomic theory revealed much about the inner structure of atoms. There is no single charge on iodine (if you are referring to its oxidizing number). The iodine atoms are added as anions, and each has a 1− charge and a mass number of 127. Write and interpret symbols that depict the atomic number, mass number, and charge of an atom or ion ; Define the atomic mass unit and average atomic mass; Calculate average atomic mass and isotopic abundance; The development of modern atomic theory revealed much about the inner structure of atoms.
