An atom consists of a nucleus containing protons and neutrons, with electrons orbiting around it. Let's examine Oxygen-16 as an example. It has an atomic number of 8, meaning 8 protons in the nucleus. Since it's a neutral atom, it also has 8 electrons. The mass number is 16, so it contains 8 neutrons. This structure determines the element's chemical properties.
The periodic table organizes elements into groups based on their properties. Group 1 contains alkali metals like lithium, sodium, and potassium, which are highly reactive. Group 2 has alkaline earth metals like magnesium and calcium. Groups 3 through 12 are transition metals with variable oxidation states. Group 17 contains halogens that form negative one ions, while Group 18 has unreactive noble gases with full electron shells.
Chemical bonding occurs in two main types. Ionic bonds form between metals and nonmetals through electron transfer, creating charged ions like sodium chloride. Covalent bonds form between nonmetals through electron sharing, like in water molecules. Many compounds show characteristic colors in solution due to electron transitions. Copper sulfate produces blue solutions, nickel chloride gives green, iron chloride appears yellow-brown, and potassium permanganate creates purple solutions.
