Verified step by step guidance1
Recall that a neutral atom has the same number of electrons as protons in its nucleus.
Identify the atomic number of hydrogen, which is 1, meaning it has 1 proton and therefore 1 electron in a neutral state.
Identify the atomic number of uranium, which is 92, meaning it has 92 protons and therefore 92 electrons in a neutral state.
Compare the number of electrons in hydrogen and uranium: hydrogen has 1 electron, uranium has 92 electrons.
Conclude that uranium has more electrons in a neutral atom than hydrogen.
