Apositive charge means: a. surplus of electrons b. lack of electrons c. excess atoms d. gained protons

A positive charge means lack of electrons.

Explanation:

Atoms that are present in all bodies, are composed of electrons, protons and neutrons. All three have mass, but only the electron and the proton have charge. The electron has a negative charge, and the proton has a positive charge.

In a neutral atom, the number of protons coincides with the amount of electrons. But it may happen that these amounts are different.

When there are excess electrons, as these have a negative charge, the charge of the element will be negative. Then an anion is formed.

However, when there is a lack of electrons, the element's charge will be positive. Then a cation is formed.

So, a positive charge means lack of electrons.
