RE: How many valence electrons does aluminum have? How do you think about the answers? As such, aluminium is the most electropositive metal in its group, and its hydroxide is in fact more basic than that of gallium. The 3P1 shell has one electron in it (in Al's neutral atom) and that gives aluminum one lone valence electron and two "semi-valence" electrons which can be loaned out. 1 1. Want to see this answer and more? check_circle Expert Answer. The symbol for aluminum is Al and has 13 protons, 13 electrons, and 14 neutrons. Aluminum atom therefore has 3 valence electrons. In metallic aluminum the three valence electrons per atom become conduction electrons. So is one of the failures of classical models and a quantum model needs development. • Group 13: Al = 3 • Group 14: C = 4 • Group 15: N = 5 • Group 17: Cl = 7 Thus, Al has the fewest valence electrons available for bonding. The most stable valence is one that fills or half-fills an atom’s electron shell. In this experiment, you will combine equal amounts of magnesium and aluminum with hydrochloric acid and compare the reactivities of the two metals. Valence electrons, on the other hand, stay farther away from the nucleus and experience much less electrostatic attraction. Problem 58 Write the name of the element with the valence el… View View Full Video. These shared valence electrons are pulled by neighboring atoms with equal and opposite forces, causing them to form a bond. As a result, these electrons are readily influenced by neighboring atoms.
