How many protons, neutrons, and electrons does a neutral atom of this element have? (round atomic mass to nearest whole number) the element is "ai" protons: 13 neutrons: 14 electrons: 13 protons: 14 neutrons: 27 electrons: 13 protons: 27 neutrons: 13 electrons: 14 protons: 13 neutrons: 13 electrons: 13

Aluminum has an atomic number of 13,  so it has 13 protons. In its natural state, it does not have a charge,  so it has an equal amount of electrons, 13. The atomic mass of aluminum is approximately 27. Since protons and neutrons make up that mass, and each of the particles are around 1 atomic mass unit, if there are 13 protons, then there are 27-13 neutrons, or 14 neutrons. So the first answer choice is correct.
