Question

which analogy best describes how electrons behave in an atom?
people standing still in a line
cars parked in a garage
riders swinging around a central post
coins inside a vending machine

an atom has 7 protons. if the atom has a net charge of 0, how many electrons does the atom have?
8
7
56

Explanation:

Step1: Understand atomic charge

An atom is neutral when the number of protons (positive charge) equals the number of electrons (negative charge).

Step2: Apply the principle

Given 7 protons and net charge 0, the number of electrons must equal the number of protons.

Answer:

7
