Question

1. which of these statements about electrons is true? a) electrons are found in the nucleus alongside protons and neutrons b) electrons have a positive charge c) electrons are about 1/1840 as massive as protons d) electrons stay completely still around the nucleus 18. what is one way that “covalent bonds” and “ionic bonds” differ?

Explanation:

• Option A is incorrect as electrons are in the electron - cloud outside the nucleus, not in the nucleus with protons and neutrons.
• Option B is incorrect since electrons have a negative charge.
• Option C is correct. Electrons have a mass of approximately 9.11×10⁻³¹ kg and protons have a mass of about 1.67×10⁻²⁷ kg, and electrons are about 1/1840 as massive as protons.
• Option D is incorrect as electrons are in constant motion around the nucleus.

Answer:

C. Electrons are about 1/1840 as massive as protons
