It keeps its neutrons but loses one electron. Protons and neutrons do not move in a chemical reaction. Sodium, being in group one, must lose one electron to have a complete outer electron shell and thus be stable.

How many electrons are in the outermost orbital in one atom of sodium?

One atom of sodium has one electron in its outermost orbital.


In reaction between bromine and sodium bromine atom gains an electron and forms the bromide ion . What happens to bromine?

Bromine loses an electron and forms a bromide ion by gaining one electron in the reaction with sodium. Sodium donates its electron to bromine, making the bromine atom gain one electron and become a bromide ion during the reaction.


How can you get an ion of bromine?

Bromine has 7 electrons in its outer shell and needs to gain one electron to have a full outer shell and become an ion. It will gain this electron from an atom that has one electron in its outer shell such as Lithium or Sodium.


How many valence electron are there in sodium neutral atom?

There is one valence electron in a neutral sodium atom. Sodium has an electron configuration of 2-8-1, indicating it has one electron in its outermost energy level.


What is the result of a sodium atom transferring an electron to a chloride atom?

The sodium atom will lose an electron and become a positively charged sodium ion, while the chloride atom will gain that electron and become a negatively charged chloride ion. These ions will be attracted to each other due to their opposite charges, forming an ionic bond to create sodium chloride, or table salt.


How many outer ring electrons does a sodium atom have?

Sodium has one electron in its outer ring.


Which of these is the correct Lewis structure for a sodium atom?

The electron-dot structure of sodium atom is 'Na-dot' or 'Na.' One dot is one valence electron.


What charge will a Sodium atom have if it loses one electron?

The Sodium atom with be positively charged [it will have a single positive charge]


How many Chlorine electrons are in the outer shell of a sodium atom?

None - the electron goes from sodium TO the chlorine.


Why does the transfer of an electron occur between a sodium atom and a chlorine atom?

The transfer of an electron between a sodium atom and a chlorine atom occurs because sodium has one electron in its outer shell that it wants to lose to achieve a more stable electron configuration, while chlorine has seven electrons in its outer shell and can gain one from sodium to complete its outer shell and achieve stability by forming a full octet. This transfer of electrons results in the formation of sodium chloride, an ionic compound.
