Determine whether each of the following statements is true or false. d. The protons in the nucleus of the helium atom are held together by a force called the strong nuclear force.

검증된 단계별 안내

Understand the composition of a helium atom: A helium atom consists of 2 protons, 2 neutrons, and 2 electrons. The protons and neutrons are located in the nucleus.

Recognize the forces at play within the nucleus: The nucleus is held together by the strong nuclear force, which is responsible for binding protons and neutrons together.

Consider the role of the strong nuclear force: This force is much stronger than the electromagnetic force, which would otherwise cause the positively charged protons to repel each other.

Evaluate the statement: The statement claims that the protons in the nucleus of the helium atom are held together by the strong nuclear force.

Determine the truth value: Since the strong nuclear force is indeed responsible for holding the protons (and neutrons) together in the nucleus, the statement is true.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Strong Nuclear Force

The strong nuclear force is one of the four fundamental forces of nature, responsible for holding protons and neutrons together in an atomic nucleus. It is a short-range force that operates at distances on the order of one femtometer (10^-15 meters) and is significantly stronger than the electromagnetic force that would otherwise cause protons, which are positively charged, to repel each other.

Atomic Structure

Atomic structure refers to the arrangement of protons, neutrons, and electrons within an atom. In a helium atom, there are two protons and two neutrons in the nucleus, surrounded by two electrons in orbitals. Understanding atomic structure is crucial for grasping how forces like the strong nuclear force operate within the nucleus.

Electromagnetic Force

The electromagnetic force is another fundamental force that acts between charged particles. In the context of atomic structure, it causes repulsion between the positively charged protons in the nucleus. The strong nuclear force must overcome this repulsion to keep the nucleus stable, highlighting the balance of forces that govern atomic stability.
