Question

below are two atomic models. each model represents a different atom.
atomic models image with proton (yellow), neutron (gray), electron (blue) legend
complete the sentence.
the two atoms represented above contain the same number of ______.
options: protons, neutrons, electrons

Explanation:

To determine the same - numbered particle, we analyze each type:

1. Protons: Count the yellow (proton) particles. The first atom has 3 protons, the second has 4 protons. So protons are not equal.
2. Neutrons: Count the gray (neutron) particles. The first atom has 3 neutrons, the second has 4 neutrons. So neutrons are not equal.
3. Electrons: Count the blue (electron) particles. The first atom has 3 electrons (1 in inner shell, 2 in outer? Wait, looking at the diagram: first atom's electrons: let's count the blue dots. First atomic model: 3 blue dots (electrons). Second atomic model: 3 blue dots (electrons). So electrons are equal.

Answer:

electrons
