Worked Solution & Example Answer:Which statement about the subatomic particles in an atom is correct? A - OCR Gateway - GCSE Chemistry - Question 1 - 2021 - Paper 3
Step 1
Identify the Correct Statement
Answer
From the options provided, the correct statement is:
D. Protons have a relative mass of one.
Explanation:
- Option A is incorrect because electrons have a very small relative mass (approximately 1/1836) compared to protons and neutrons.
- Option B is incorrect because electrons are not found in the nucleus; they orbit around it.
- Option C is incorrect because neutrons have no charge (they are neutral).
Thus, option D correctly states that protons have a relative mass of one, aligning with standard atomic theory.
