Understanding Aluminum: Bohr Model, Valence Electrons, and Atomic Theory

This document explores key concepts related to the aluminum atom, including the Bohr model representation that illustrates its 13 electrons and protons, and 14 neutrons. It identifies the number of valence electrons in aluminum, which can be deduced from the Bohr model. The origins of atomic theory are examined, highlighting John Dalton as the developer of the first atomic theory. Additionally, it addresses the misconception about atoms, clarifying if they are the sole building blocks of living things.
