Step-3: A. Lewis dot structure for an atom of chlorine is . Since it has 7 valence electrons in it's outermost shell and it needs one electron to complete it's octet. Answer: Each chlorine has 7 valence electrons. The general formula is that the nth shell can in principle hold up to 2(n 2) electrons. Periodic Table of Elements with Valence Electrons Trends. How many electrons are in Cl ion? The group valence of the elements is generally either equal to the number of dots in Lewis symbols or 8 minus the number of dots or valence electrons. The atomic number of chlorine is 17. The below is the image for the valence shell of chlorine which converts into chloride ion. The atomic number of Cl is 17 and its simple electron arrangement is 2, 8, 7 …The region containing 7 electrons is called valence shell and remaining 10 electrons constitute core electrons…Thus Cl has core of Ne… Step-by-step explanation: Chlorine is an element with atomic number 17 and thus contains 17 electrons.Valence electrons are the electrons which are present in the valence shell. What is shown here is only the Valence electrons. When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na +) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. Electrons in the outer shells that are not filled are called valence electrons. Valence electrons. The atomic number of chlorine is 17. An atom such as chlorine (Cl), that contains seven electrons in its valence shell, needs one more electron to have a full valence shell. 18 electrons If we use the same logic as we did for sodium, we should conclude that chlorine would rather gain one more electron than lose all seven of its valence electrons … In contrast, chlorine and sodium have seven and one electrons in their.A Bohr diagram depicts an atom with a small, central nucleus and the electrons in their valence shells. We know that the atomic number of chlorine is 17.So chlorine has 17 protons and 17 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1. The number of valence electrons for an atom is the number of electrons in the outer energy level (shell) of the atom. Hence, it's valency is -1. Chlorine’s electron configuration is 2-8-7; therefore it has seven valence electrons and needs to have seven dots drawn around its symbol. For facts, physical properties, chemical properties, structure and atomic properties of the specific element, click on the element symbol in the below periodic table. Hence it has 2 electrons in its inner-most shell, 8 electrons in its second shell and 7 electrons in outer-most shell respectively. Cl is 17 and it's electronic configuration is 2,8,7. The first valence shell contains 2 electrons, and the second and third shell have 8 electrons each, and the number keeps growing.
