Hydrogen is in the first row and the first column of the periodic table. Hydrogen does not have any neutrons. Hydrogen does not have any neutrons. Hydrogen is stable, with two electrons in its outer shell.

Answer 1

The statement that best explains why hydrogen’s atomic number is equal to its mass is: "Hydrogen does not have any neutrons."

This is because hydrogen has an atomic number of 1, which means it has one proton and, in its most common isotope, no neutrons. The mass number of this isotope is also about 1 (only considering the proton), making the atomic number equal to its mass.
