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.
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 [tex]Ca^{2+}[/tex].
Hence, it means that by loosing 2 valence electrons calcium has an electric charge of +2.
