Apolonium atom has 84 protons, 124 neutrons, and 84 electrons. what will it change to during alpha decay? a. a lead atom with 82 protons, 122 neutrons, and 84 electrons b. a bismuth atom with 83 protons, 123 neutrons, and 84 electrons c. a polonium atom with 84 protons, 124 neutrons, and 85 electrons d. an astatine atom with 85 protons, 123 neutrons, and 84 electrons

Option (A) is the correct answer.

Explanation:

An alpha particle is a helium atom that is represented as .

Therefore, when an alpha decay occurs if polonium atom has 84 protons, 124 mass, and 84 electrons. Then the reaction will be as follows.

An element with atomic number 82 is lead.

Thus, we can conclude that when a polonium atom has 84 protons, 124 mass, and 84 electrons then it will change to a lead atom with 82 protons, 122 mass, and 82 electrons during alpha decay.

1. they vary with a higher number because boiling is way hotter than melting

i'm wiling to try and you : )
