Electrons have electric charge of -1 and the number of electrons in an atom is equal to the number of protons. ... Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.

Why an atom is electrically neutral Class 9?

Hint: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or losses one or more electrons, it becomes an ion. Complete answer: ... A neutral atom is an atom that has no charge.

Why an atom is electrically neutral short answer?

Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.
