Which of the following statements is correct?
A neutron has no electrical charge.
The central part of an atom contains only protons.
The central part of an atom contains only neutrons.
The central part of an atom contains only electrons.
A neutron has no electrical charge.
A neutron is a subatomic particle found within the atomic nucleus that possesses no electrical charge, making it electrically neutral. In contrast, protons carry a positive charge and electrons carry a negative charge.
A neutron is a subatomic particle found within the atomic nucleus that possesses no electrical charge, making it electrically neutral. In contrast, protons carry a positive charge and electrons carry a negative charge.
Think of a neutron as a 'peacekeeper' in the nucleus; while protons are 'charged' individuals prone to repulsion, neutrons act as the neutral buffer that helps hold the structure together.
PEN: Proton (Positive), Electron (Negative), Neutron (Neutral).

The atomic nucleus is composed of protons and neutrons (collectively known as nucleons), which are held together by the strong nuclear force. While protons have an electrical charge of +1.602├Ч10тИТ19┬аC, neutrons have a net charge of 0┬аC, providing the necessary mass and binding stability to the nucleus without contributing to electrostatic repulsion.
Neutrons reside in the nucleus along with protons.
The mass of a neutron is slightly greater than the mass of a proton.
Neutrons are essential for the stability of the atomic nucleus.
An atom is electrically neutral overall if the number of electrons equals the number of protons.
Neutrons stabilize the nucleus by counteracting the electrostatic repulsion between protons.
Free neutrons are unstable and undergo beta decay with a half-life of approximately 10.2 minutes.

Mass of neutron mnтАЛтЙИ1.6749├Ч10тИТ27┬аkg.
Option B is incorrect as the nucleus contains both protons and neutrons.
Option C is incorrect as hydrogen nucleus contains only a proton.
Option D is incorrect as electrons orbit the nucleus in specific energy levels.
A is correct тАФ A neutron is a subatomic particle that carries no net electrical charge.
Always remember that the 'nucleus' refers to the center containing nucleons; electrons are always 'extranuclear'. In competitive exams, remember that a hydrogen-1 isotope is the only nucleus without a neutron.
