An electron density shell is made up of electrons, so if you remove the electrons, there is no shell anymore. After sodium is ionized, the. elements in group 0 do not easily react and form compounds. Hence stable and inert if it could get one more electron and complete its valence or outermost The properties of Na+ ion and the sodium atom are different from each other. What is the number of valence electrons in (a) sodium ion (Na+)? each having two valence electrons in their valence shells, are in periods 2.
You determine the valence electrons by using the Periodic Table. The electron configurations of ions are those of the neutral atoms plus or minus a number of For Na+: . How many valence electrons does sodium have?. Sodium, like all the group 1 alkali metals, has one valence electron. Most atoms do not have eight electrons in their valence electron shell. table becomes a tool for remembering the charges on many ions.
What is the no. of valence electrons in sodium ion(Na+) Oxide ion(O2-) Given atomic no. of Na=11 O=8 Get the answers you need, now!. A)An atom of a group 1 element such as sodium has just one valence electron. It is “eager” to give up this electron in order to have a full outer. For Sodium Na - 2,8,1 and chlorine Cl-2,8,7. Both Na and Cl require 1 electron either to loose or to gain,so they can attain stable configuration. Therefore Na.
