Sodium, like all the group 1 alkali metals, has one valence electron. Valence electrons are the outermost electrons, and are the ones involved in bonding. Sodium has 11 electrons: its atomic number is 11, so it has 11 protons; atoms are neutral, so this means sodium also has 11 electrons. Electrons are arranged in "shells" or energy levels.


In solution, the sodium and chlorine atoms separate to form sodium and chlorine ions, but the sodium valence electron stays with the chlorine atom. As a result, the sodium ion has a complete outermost electron shell of eight electrons and a positive charge of plus 1.


In chemistry, valence electrons are the electrons that are located in the outermost electron shell of an element. Knowing how to find the number of valence electrons in a particular atom is an important skill for chemists because this information determines the kinds of chemical bonds that it can form and, therefore, the element's reactivity.


sodium has 1 valence electron +1 lead is a transition metal that means he has variable osidation state but the stable one is 2 valence electron +2 phosphorus has 5 valence electron +5 chlorine has 7 valence electron -1 berryllium has 2 valence electron +2


Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus. Valence electrons are of crucial importance because they lend deep insight into an element’s chemical properties: whether it is electronegative or electropositive in nature, or they indicate the bond order of a chemical compound – the number of bonds that can be formed between two atoms.


The number of valence electrons. The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized. With the exception of groups 3–12 (the transition metals), the units digit of the group number identifies how many valence electrons are associated with a neutral atom of an element listed under that particular column.

Determine the number of valence electrons for sodium through the use of this table. Na: 1. ... Using the ideas from this section and the periodic table, choose the more reactive metal. Al or Zn. Zn. Using the ideas from this section and the periodic table, choose the more reactive nonmetal. F or Cl. F.


The valence of sodium is one. Sodium has a valence of one because it only has one electron present on its outermost shell. The outermost shell of an atom is also known as its valence shell. Sodium has an atomic number of 11, meaning that 11 electrons orbit around the nucleus of the atom.
