Question

question 11 (6 points)
atoms have positively charged particles, negatively charged particles, and particles with no charge. why is an atom electrically neutral?
o a atoms have neutrons and protons in the nucleus, and they do not have a charge.
o b atoms contain subatomic particles and not electrically charged particles.
o c an atoms nucleus has only neutrons, which have no charge.
o d atoms have the same number of electrons (negative charge) and protons (positive charge).

Explanation:

• Option a: Protons have a positive charge, so this is incorrect.
• Option b: Atoms do contain subatomic particles (protons, neutrons, electrons), but this statement doesn't explain electrical neutrality.
• Option c: Nucleus contains protons (positive charge) and neutrons (no charge), so this is incorrect.
• Option d: Electrons (negative charge) and protons (positive charge) are equal in number, so their charges cancel out, making the atom electrically neutral.

Answer:

d. Atoms have the same number of electrons (negative charge) and protons (positive charge).
