The periodic table arranges elements based on increasing atomic number, which represents the number of protons in the nucleus of an atom. The elements within the same column (group) of the periodic table share similar chemical properties due to having the same number of electrons in their outer shell. The first 30 elements are critical for understanding the structure and reactivity of matter. Elements such as hydrogen and helium are classified as nonmetals, whereas elements like lithium, sodium, and potassium are metals. Transition elements, such as iron and copper, are known for their ability to form various oxidation states. Each element has unique properties, with their atomic number and electron configuration determining their behavior in chemical reactions.
