The valence of an electron means the total number of electrons present in the outermost shell of an electron which can be shared with the other elements to form a chemical bond. For example: Valence electrons in Na are 1. Valence electrons in Cl are 7. Valence electrons in H are 1 The combining power of one atom of an element (or a radical), that of the hydrogen atom being the unit of comparison, determined by the number of electrons in the outer shell of the atom (v. electrons); e.g., in HCl, chlorine is monovalent; in H 2 O, oxygen is bivalent; in NH 3, nitrogen is trivalent. Jan 22, 2020 · The Atomic number of chlorine I.e. Cl is 17 and it's electronic configuration is 2,8,7. Since it has 7 valence electrons in it's outermost shell and it needs one electron to complete it's octet. Hence, it's valency is -1.

Animal abuse reddit/• Atoms of chlorine have seven valence electrons. – A gain of one electron gives a chlorine atom an octet and converts a chlorine atom into a chloride atom. Atoms of nonmetallic elements attain noble-gas electron configurations more easily by gaining electrons than by losing them because these atoms have relatively full valence shells.

For example, take a look at chlorine again. It has 17 electrons. How many are in the valence? The first two levels will be full with 10 electrons. That means there are seven electrons left in the valence shell. This means that chlorine wants to gain an electron in order to have a complete valence shell.

A: An atom of a group 17 element such as chlorine has seven valence electrons. It is “eager” to gain an extra electron to fill its outer energy level and gain stability. Group 16 elements with six valence electrons are almost as reactive for the same reason. Atoms of group 18 elements have eight valence electrons (or two in the case of helium). The combining power of one atom of an element (or a radical), that of the hydrogen atom being the unit of comparison, determined by the number of electrons in the outer shell of the atom (v. electrons); e.g., in HCl, chlorine is monovalent; in H 2 O, oxygen is bivalent; in NH 3, nitrogen is trivalent. Since chlorine's outermost orbital is a 3p orbital, there is more space, and the electrons in this orbital are inclined to share this space with an extra electron. Therefore, chlorine has a higher electron affinity than fluorine, and this orbital structure causes it to have the highest electron affinity of all of the elements. 3.1-3. Valence Electron Configurations of Main Group Elements All of the elements in a group have the same number of valence electrons (Group number), and their valence electron configurations are the same except for the value of the n quantum number (the period).
