Guida verificata passo dopo passo1
Understand that a neutral atom has an equal number of protons and electrons.
Identify the atomic number of each element, which equals the number of protons (and electrons in a neutral atom).
Look up the atomic numbers: Oxygen (O) has 8, Gold (Au) has 79, Lead (Pb) has 82, and Uranium (U) has 92.
Compare these atomic numbers to determine which element has the greatest number of electrons in its neutral state.
Conclude that the element with the highest atomic number has the greatest number of electrons in a neutral atom.
