Question

What is the overall electric charge for individual atoms on the periodic table of elements?

Answer 1

Explanation:

All the atoms present in periodic table are neutral in nature and it is known that a neutral atom means that it contains no charge.

For example, sodium is present as Na in the periodic table. And, it does not contain any charge.

When a neutral atom loses or gains an electron then it acquires a charge.

For example, atomic number of calcium is 20 and its electronic distribution is 2, 8, 8, 2. Hence, in order to acquire stability when it loses 2 valence electrons then neutral atom of Ca changes into $Ca^{2+}$.

Hence, it means that by loosing 2 valence electrons calcium has an electric charge of +2.

Answer 2

Answer:

Neutral

Explanation:

Atoms on the periodic table all have neutral electric charges. This is because they have an equal number of protons, which are positivly charged, and electrons, which are negatively charged.
