Potassium is the seventh most abundant element in the Earth's crust. But what is potassium most similar to? The answer lies in the periodic table's Group 1, the alkali metals, which share comparable chemical and physical properties.

With an atomic number of 20, calcium (Ca) is the fifth most abundant element in the Earth's crust, but did you know its position on the periodic table defines its chemical behavior? If you want to know in which group will you find calcium, the answer is Group 2, a classification that explains its high reactivity and metallic properties.

With an atomic number of 12, magnesium possesses 12 electrons, which are arranged in distinct energy shells. Understanding these electron shells is key to answering what is the highest energy level of magnesium, which corresponds to the location of its outermost electrons. These outer electrons are the primary drivers of an element's chemical behavior, determining how it interacts with other atoms.
