steel is 20 x 10 11 N/m 2
O 65 x 10-6m
O 56 x 105 m
O 56 x 10-6 m
O 6.5 x 10-5 m
O 6.5 x 10-4 m

It won't lose or gain electrons if it's a covalent bond it shares the electrons with another atom or atoms. if it is an ionic bond it will lose the 3 electrons on the outer shell and become a positively charged ion.  credit goes to @sunshinebaby of answers.yahoo.com.
