Which part of an atom is actively exchanged or shared in a chemical bond? a. proton b. electron c. neutron d. depends on the type of atom

The part of an atom that is actively exchanged or shared in a chemical bond is the;

B. Electron

Electrons are negatively charged atoms.The electron is actively exchanged in a chemical bond

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
