#Sodium element electrons free#

Metals group and valency of alkali metals are always 1. as sodium is an element of group 1 which indicated alkali We can also find the valency of sodium with the help of a periodic table. Gas configuration) by losing one outermost electron. noble gases).Īlkali metals like sodium reached the stable (nearest inert Possess both positive and negative valency and atom having eight outermostĮlectrons have zero valencies (i.e. Outermost shells is between one to four, the atom has positive valency and ifĮlectrons are between four to eight, the valency is calculated by subtractingįrom eight and valency is negative. Valency of an atom is determined based on the number of electrons lost, gained, or shared with another atom.Īn atom is said to be stable when its outermost shells haveĮight electrons (except H and He).

How easily an atom or a free radical can combine with other chemical species. There are many different ways to find out the valency of anĪtom which reflects the ability of an atom to bond with other atoms. In the valence shell of sodium ( 3 s 1 ). Of an atom is called valence electrons, and there is only one electron present The total number of electrons present in the valence shell Sodium electron configuration Na (11) = 1 s 2 2 s 2 2 p 6 3 s 1 (completeĬonfiguration) or 3 s 1 (condensed configuration).Īs we know, the valence shell of an atom can be found from the highest number of principle quantum numbers which is expressed in the term of nĪnd in 1 s 2 2 s 2 2 p 6 3 s 1, the highest value of n is 3 so that the valence shell of Now the extra one will go into the 3S orbital. Orbital and the next six electrons will go in 2p orbital as P orbital can only Orbital can hold a maximum of two electrons only. The first two electrons will go in the 1s orbital as S The sodium atom has a total of 11 electrons, so we have to put 11Įlectrons in orbitals. Less) in any condition for a particular atom and may or not be equal to itsĮlectron configuration is the arrangement of electrons on the The valenceĮlectrons for a neutral atom is always definite, it cannot be varied (more or Valence electrons are the total number of electrons present You have to know what these two terms are, so without wasting your time let's goįor it, Difference between valence electrons and valency Know what valence electrons and valency of sodium are, aren’t you? But for this Is not found in a free state in nature due to its high reactivity behavior so that it is abstracted from different compounds (mostly from salts).Īs we know how much sodium is being used in the world ofĬhemistry, so we must have very good proper information about its electronic properties to survive in the world of chemistry and that’s why you are here to Reactive alkali metals of group 1 with atomic number 11 in the periodic table. Sodium, a chemical element with symbol Na, is one of the highly
