Question

15 multiple choice 5 points the image shows a model for a lithium atom: how many neutrons are in this lithium atom? 7 4 10 3

Explanation:

Step1: Identify neutrons in model

In an atomic - model, neutrons are uncharged particles in the nucleus. Usually, protons are represented with a positive - charge symbol and neutrons are just spheres without a charge symbol. In the given lithium atom model, count the number of uncharged spheres in the nucleus.

Step2: Count the neutrons

By counting the uncharged spheres in the nucleus of the lithium atom model, we find there are 4 neutrons.

Answer:

4
