Question

cora wants to draw a model of an atom for her project for the science fair. she wants to draw an atom that has two protons, four neutrons, and two electrons. which model is like coras?

Explanation:

Step1: Identify proton - neutron - electron count

Protons are usually represented by blue spheres with a + sign, neutrons by red spheres, and electrons by green spheres in simple atom models.

Step2: Check each model

We need to find a model with 2 blue spheres (protons), 4 red spheres (neutrons), and 2 green spheres (electrons).

Answer:

The model that has 2 blue spheres in the nucleus (protons), 4 red spheres in the nucleus (neutrons), and 2 green spheres in the electron - shell is the correct one. Without specific labels for each model, we can't point out a particular one by name, but you should look for the one that matches the above - described particle counts.
