Question

Which element will donate 3 electrons ​

Answer 1

Answer:

The atomic number of aluminium is 13. In the outermost orbit of aluminium atom, 3 electrons are present. Hence, after donating 3 electrons its forms Al +3 ions, now the number of electrons is 10 and the number of protons is 13. hence, it carries a positive charge. The atomic number of chlorine is 17. The outermost orbit of chlorine atoms 7 electrons is present. It accepts one electron and forms Cl − ions, the number of electrons now is 18 and the number of p

Answer 2

Answer:

Any element which has valence +3 can donate 3 e- . Or we can say has 3 e- in its outer shell.

Explanation:

For example:- Al has valence +3 so it can give or donate 3 e-.
