When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. ...

There are 3 kinds of contraction in skeletal muscle:
Concentric contraction: The muscle in this contraction will gives force more than the load gives. This will make the muscle shorten as it pulling the load.
Eccentric contraction: In this contraction, the force given by muscle is not enough to pull the load. This causes the load pulling the muscle instead. So the muscle will be lengthened as the load moving away.
Isometric contraction: In this contraction, the length of the muscle will be kept same by adjusting the force given to be equal to the force needed.
