In which of the following situations would the least work have been done?
a. a 100-n force lifts an object 3 m.
b. a 250-n force moves an object 1 m.
c. a 25-n force moves an object 8 m.
d. a 600-n force is applied to an object and moves it 0 m.

Work = (magnitude of the force) x (distance in the direction of the force)

A 100-N force lifts an object 3 m.                ==>  (100 x 3) = 300 joules

B. A 250-N force moves an object 1 m.      ==>  (250 x 1) = 250 joules

C. A 25-N force moves an object 8 m.        ==>  (25 x 8)  =  200 joules

D. A 600-N force is applied to an object
    and moves it 0 m.                                   ==>  (600 x 0) = no work
                                                                           Winner ! Least work.

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.
