Question

1. which statement accurately describes an electron?

a subatomic particle with a positive charge located in the nucleus.
a subatomic particle with a negative charge located in the nucleus.
a subatomic particle with a negative charge located outside the nucleus.
a subatomic particle with no charge located outside the nucleus.
clear all

Explanation:

To determine the correct statement about an electron, we recall atomic structure: electrons are subatomic particles with a negative charge and are located outside the nucleus (in electron clouds). Let's analyze each option:

• Option 1 (positive charge, nucleus): Protons have positive charge in nucleus, so incorrect.
• Option 2 (negative charge, nucleus): Neutrons have no charge, protons positive in nucleus; electrons are outside, so incorrect.
• Option 3 (negative charge, outside nucleus): Matches electron's properties (negative charge, located in electron cloud outside nucleus).
• Option 4 (no charge, outside nucleus): Neutrons have no charge but are in nucleus, so incorrect.

Answer:

The correct option is the third one (labeled as "A subatomic particle with a negative charge located outside the nucleus."). If we assume the options are ordered from top to bottom as Option 1, Option 2, Option 3, Option 4, then the answer is the third option (e.g., if the third option is the one with "A subatomic particle with a negative charge located outside the nucleus", then: 3. A subatomic particle with a negative charge located outside the nucleus)
