Lithium, a chemical aspect with the price Li, is among the highlyreactive alkali metals of group 1 through an atom number 3 in the routine table. Lithium is not discovered in a complimentary state in nature as result of its high reactivity behavior so the it is abstracted from various compounds (mostly from salts). Lithium is the lightest metal ever found which has a thickness around half of water.

You are watching: How many valence electrons does lithium have

As us know how much lithium is being provided in the people ofchemistry, so us must have very an excellent proper information about its digital properties to endure in the world of chemistry and that’s why girlfriend are right here toknow what valence electrons and valency that lithium are, aren’t you? but for thisyou need to know what these two terms are, so there is no wasting your time let"s gofor it,

Difference in between valence electrons and valency

Valence electrons room the total variety of electrons presentin the outermost shell of an atom (i.e. In outermost orbital). The valenceelectrons because that a neutral atom is always definite, it cannot be differed (more orless) in any type of condition for a certain atom and also may or no be equal to itsvalency.


Valency is defined as the total number of electrons one atomcan lose, gain, or share at the time of bond formation to obtain astable digital configuration i.e. To complete an octet. The valency of one atom canbe change in different compounds or in chemistry reactions due to various bondingmechanisms.

Lithium (Li) valence electrons

There are four an easy steps to find out the valence electrons for lithium atom which are:

Step 1: find the atom Number


To find out the atomic variety of lithium, we have the right to use the periodictable. Through the aid of the regular table, we can easily see that the atomic variety of lithium is 3. As its atomic number is 3, it has a complete of 3 protons, and also forneutral lithium, the number of protons is constantly equal come the number of electronsi.e. 3 electron in the nucleus.

Step 2: compose Electron Configuration


Electron configuration is the setup of electron on theorbitals. The lithium atom has actually a complete of 3 electrons, therefore we need to put 3 electrons in orbitals. The an initial two electrons will go in the 1s orbital as Sorbital have the right to hold a best of 2 electrons only. The staying one will go in 2sorbital. Now wehave,

Lithium electron construction Li (3) =1s22s1(completeconfiguration) or2s1(condensed configuration).

Step 3: identify Valence Shell

As us know, the valence shell of an atom have the right to be found from the highest number of principle quantum number which is to express in the ax of n, and in1s22s1, the highest possible value that n is 2 so the the valence shell of Li is 2s1.

Step 4: uncover Valence Electrons

The total variety of electrons existing in the valence shellof an atom is dubbed valence electrons, and there is only one electron presentin the valence shell of lithium (2s1). Thus, lithium has actually only one valenceelectron.

Valency that Lithium (Li)

There are many different methods to find out the valency of anatom which shows the capability of one atom come bond with various other atoms. Valence describeshow easily an atom or a free radical can incorporate with other chemical species. Thevalency of one atom is determined based on the variety of electrons lost, gained, or shared with another atom.

An atom is claimed to it is in stable as soon as its outermost shells haveeight electron (except H and also He). If the total variety of electrons inoutermost shells is in between one come four, the atom has actually positive valency and ifelectrons are between four come eight, the valency is calculated by subtractingfrom eight and valency is negative. Atoms having 4 outermost electronspossess both hopeful and an unfavorable valency and also atoms having eight outermostelectrons have actually zero valencies (i.e. Noble gases).

Alkali metals prefer lithium reached the secure (nearest inertgas configuration) by shedding one outermost electron. So the the valency of lithium (Li) is 1.

We can also find the valency the lithium v the help of a regular table. As lithium is an element of group 1 which shown alkalimetals group and also valency of alkali metals are always 1.

Valence electrons and valency the Li+

Lithium-ion Li+ means it has actually lost one electron and also has just 2 electron in the orbitals. The electron configuration of neutral Li is1s22s1but in Li+ it loser one electron, so it has a new electron construction of1s2means Li+ has only 2 outermost electron which provides it stable. Thus, lithium-ion (Li+) has actually eight valence electrons.

Li+ valency is no zero like noble gas together their outermostshell has eight electrons. Once a lithium atom loses one electron, Li+ ion is produced and also that’s what valency is. So that Li+ valency is +1, no zero.
