Question

jenny is given a table of the results of the interactions of four subatomic particles. the data in the table state the effect of bringing the particles close to one another, two at a time. particle interaction

if particle 1 is an electron, what are particles 3 and 4?
a. particle 3 is a neutron. particle 4 is a proton.
b. particle 3 is a proton. particle 4 is a neutron.

trial
1 2 3

particles
1 and 2 2 and 3 3 and 4

interaction
attraction repulsion no interaction

Explanation:

Step1: Recall charge - interaction rules

Opposite charges attract, like charges repel, and neutral particles have no interaction with charged particles. An electron has a negative charge.

Step2: Analyze interaction of Particle 1 (electron) with others

Since Particle 1 and 2 attract, Particle 2 must be positively - charged (a proton). Since Particle 1 and 3 repel, Particle 3 must be negatively - charged (an electron). Since Particle 3 and 4 have no interaction, Particle 4 must be neutral (a neutron).

Answer:

A. Particle 3 is a neutron. Particle 4 is a proton.
