Question

what happens to a element A if its atom gains 2 electrons ?

Answer 1

Hello friend here's your answer

When atom A gains two electrons it forms an anion by developing 2 negative charges over it as there are 2 electrons more than the number of protons in the ion.
The overall equation is like
A+ 2e- -------》 A2e-

Answer 2

hii friend
here's your answer looking for

=>As we know that the atom is electrically neutral and the number of positive charged particle or protons and negatively charged particle or electrons are equal is number.

So, when the atom losses or gains some electrons it changes into ions or became charged.

So, we came to that , these gaining and lossing of electron causes the charge in it.

=>So, if a electron is loss by an atom then this results as the decrease in negative charge means, that the positive charge is more as compared to negative charge.
hence, that atom get positively charged because of the deficiency of electron particles or negatively charged particle of atom.

=>Similarly , if electron is gained by an atom then this results as the increase in positive charge means, that the negative charge is more as compared to positive charge.
hence, that atom get negatively charged because of the excess of electrons particle for negatively charged particle of that atom.

so we can conclude that ,more electrons increase the negative charge and less electron decrease the negative charge.

=>So, as you are asking about " what happens to a element A if its atom gains two electrons?"

So, your answer is ,

=>if the element A gains 2 electron then the element A get 2units of negative charge means it have the 2 excess of electrons or it get 2units of negatively charged particle.
hence, it get negatively charged.
