The subatomic particle with the least mass
(a) Carries a negative charge
(b) Carries a positive charge
(c) Plays no part in the atom's chemical reactions
(d) Is found only in the nucleus

검증된 단계별 안내
1
Step 1: Identify the three main subatomic particles in an atom: electrons, protons, and neutrons.
Step 2: Recall the relative masses of these particles: electrons have the least mass, protons and neutrons have much greater mass.
Step 3: Understand the charges of these particles: electrons carry a negative charge, protons carry a positive charge, and neutrons are neutral (no charge).
Step 4: Consider the location of these particles: electrons orbit the nucleus, while protons and neutrons are located in the nucleus.
Step 5: Analyze the options in the problem based on the above information to determine which statement correctly describes the subatomic particle with the least mass.

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

Subatomic Particles and Their Masses

Atoms are composed of three main subatomic particles: electrons, protons, and neutrons. Among these, the electron has the least mass, approximately 1/1836 that of a proton or neutron, making it the lightest particle within the atom.

Electric Charge of Subatomic Particles

Each subatomic particle carries a specific electric charge: electrons are negatively charged, protons are positively charged, and neutrons have no charge. This charge influences how particles interact and bond chemically.

Role of Electrons in Chemical Reactions

Electrons, especially those in the outermost shell (valence electrons), are primarily responsible for chemical bonding and reactions. Protons and neutrons, located in the nucleus, do not directly participate in chemical reactions.
