Alkali metals, Highly reactive metals, low density, and soft, silvery appearance, Alkaline earth metals, Shiny, silvery-white, and highly reactive metals, notable for having two valence electrons and forming \(+2\) cations, Transition metals , Located in the middle of the periodic table, they are hard, dense, and lustrous, with high melting and boiling points, acting as strong conductors of electricity and heat, Metalloids, Characterized by having intermediate properties between metals and nonmetals, specifically a metallic luster combined with brittleness, Halogens, Highly reactive, colored nonmetals characterized by having seven valence electrons, making them "eager" to gain one electron to achieve a stable octet., Nobel gas, Extremely stable due to a full valence electron shell, making them inert or nonreactive under normal conditions., Metals, High electrical and thermal conductivity, lustrous/shiny appearance, with good structural strength. They are typically malleable and ductile due to their metallic bonding, Non-metals , Poor conductors of heat and electricity, brittle in solid form, and non-malleable. Can exist as solids, liquids, or gases with low melting and boiling points.
