Which is an example of a covalent bond?

select one of the options below as your
a. chlorine accepts an electron from calcium to form a stable bond.
b. ions in a bar of pure iron are surrounded by a large number of valence electrons.
c. there are less than 16 valence electrons in 2 chlorine atoms, but they form a stable bond.

The correct answer is definitely C. There are less than 16 valence electrons in 2 chlorine atoms, but they form a stable bond because a covalent bond should involve a pair of electrons between atoms in a molecule. I thing it's pretty clear. Regards!

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
