question select the correct answer from each drop - down menu. if an atom has 7 protons, 8 neutrons, and 10 electrons, then it has a net charge of. on the other hand, if an atom has 3 protons, 3 neutrons, and 2 electrons, its net charge is.

question select the correct answer from each drop - down menu. if an atom has 7 protons, 8 neutrons, and 10 electrons, then it has a net charge of. on the other hand, if an atom has 3 protons, 3 neutrons, and 2 electrons, its net charge is.

Answer

Explanation:

Step1: Recall charge of sub - atomic particles

Protons have a charge of + 1, neutrons have a charge of 0, and electrons have a charge of - 1.

Step2: Calculate net charge for first atom

For an atom with 7 protons, 8 neutrons, and 10 electrons, the net charge $Q_1$ is calculated as $Q_1=(+1)\times7+(0)\times8+(-1)\times10=7 + 0-10=-3$.

Step3: Calculate net charge for second atom

For an atom with 3 protons, 3 neutrons, and 2 electrons, the net charge $Q_2$ is calculated as $Q_2=(+1)\times3+(0)\times3+(-1)\times2=3 + 0 - 2=+1$.
