Period number of aluminum
WebJan 30, 2024 · The increase from Group 2 to Group 3 is offset by the fall as you go down Group 3 from boron to aluminum. Something similar happens from lithium (1.0) to magnesium (1.2), and from boron (2.0) to silicon (1.8). In these cases, the electronegativities are not exactly the same, but are very close. WebApr 7, 2024 · Complete step by step answer: Aluminum is the chemical element present in the periodic table in group 13 and period 3. It is a p-block element. The atomic number of aluminum is 13 which means that the number of protons present in aluminum is 13 and the number of electrons present in aluminum is 13.
