Question

atom diagram
use the diagram below to answer the questions.

1. which object in the diagram has a positive charge?
2. which letter correctly identifies the mass of the atom?
3. which letter represents the electron cloud?
4. which letter on the diagram identifies the subatomic particle that has relatively no mass?
5. which letter correctly identifies the neutron?

Explanation:

Step1: Match charge to particle

Protons (E) have a positive charge.

Step2: Locate atomic mass source

Most atomic mass is in the nucleus (B), holding protons/neutrons.

Step3: Identify electron cloud region

The outer area (A) is the electron cloud.

Step4: Find near-massless particle

Electrons (C) have negligible relative mass.

Step5: Locate neutral subatomic particle

Neutrons (D) are the neutral nucleus particles.

Answer:

1. E
2. B
3. A
4. C
5. D
