Which of the following statements is wrong?

Options

A. Protons are present in the nucleus of an atom.
B. Electrons are negatively charged
C. The mass of a neutron is nearly equal to the mass of a proton.
D. Electrons are neutral.

Answer

To determine which of the following statements is wrong, we will evaluate each statement one by one.

1. **Statement 1**: Protons are present in the nucleus of an atom.
- **Evaluation**: This statement is true. Protons are indeed located in the nucleus of an atom, along with neutrons.

2. **Statement 2**: Electrons are negatively charged.
- **Evaluation**: This statement is also true. Electrons carry a negative charge, specifically -1.6 × 10^-19 coulombs.

3. **Statement 3**: The mass of a neutron is nearly equal to the mass of a proton.
- **Evaluation**: This statement is true as well. The mass of a neutron is approximately equal to the mass of a proton, both being around 1.67 × 10^-27 kg.

4. **Statement 4**: Electrons are neutral.
- **Evaluation**: This statement is false. Electrons are not neutral; they have a negative charge.

Based on the evaluations, the wrong statement is:

**Answer**: Option 4 - Electrons are neutral.
