Atoms with fewer than 4 valence electrons want to give away their electrons to become what

Stable, Cation, Donor Atom

Explanation:

When an atom has less than 4 electrons in its valence shall, it tends to lose those electrons to becomes stable. Because an atom becomes stable when its valence shell is complete. So, when it loses the electrons its valence shell becomes complete. Also, after the loss of the electrons a positive charge is developed on the atom and it becomes an cation or donor atom.

Hence, there can be multiple answers to this question.

Atoms with fewer than 4 valence electrons want to give their electrons to become Stable, Cation, Donor Atom.

The gravitational potential energy is calculated by the product of mass of the object, gravitational acceleration and the height or the elevation of the object. We calculate as follows:

PE = mgh
8.0 J = .055 kg (9.81 m/s^2) (h)
h = 14.83 m

Hope this helps.
