11. What is the force between two electrons

The attractive force between the electrons and the nucleus is called the electric force.

Explanation:

Electric force

Explanation:

The attractive force between the electrons and the nucleus is called the electric force.Experiments have shown that the electric force between two objects is proportional to the inverse square of the distance between the two objects.

passing a magnet thought the

mixture , because iron gets attracted to magnet .

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
