(iv) Carbon anode is used when molten magnesium chloride is electrolyzed. Therefore, they have similar chemical properties because chemical properties are dependent on electronic configuration of an element. (iv) As the two atoms in (iii) above are isotopes and hence have same electronic configuration. Hence, its electronic configuration = 2, 8, 7 17 electrons (green) bind to the nucleus, successively occupying available electron shells (. (ii) Atomic number of Chlorine is 17 so it has 17 electrons. The nucleus consists of 17 protons (red) and 18 neutrons (blue). Positive charges - in the nucleus of it's atomĪn atom is the smallest particle of an element which can take part in a chemical reaction and is considered the basic unit of matter.Be Name of Element : Berylium Atomic Weight : 9. Li Name of Element : Lithium Atomic Weight : 6.9 Atomic Number : 3 Group : Alkali Metals Electron Configuration: 1s2 2s1 Go to the Top of the page. (i) Atomic number of an element is the number of : Electron Configuration: 1s2 Go to the Top of the page. Chlorine is a chemical element of the periodic table with chemical symbol Cl and atomic number 17 with an atomic weight of 35.
