Group IA: Alkali Metals
Group IIA: Alkali‐Earth Metals
Group 3‐12: Transition Metals
• Group contains: Metals • Electrons in outer level: 1 • Reactivity: Very reactive • Shared properties: softness, silver color, shininess, low density
{
{
• Group contains: Metals • Electrons in outer level: 2 • Reactivity: Very reactive (but less than Alkali Metals) • Shared properties: silver color, higher densities than alkali metals.
• Group contains: Metals • Electrons in outer level: 1 or 2 • Reactivity: Less than Alkali‐Earth Metals • Shared properties: shininess, good conductors of thermal energy and electric current, higher densities and melting points than elements from groups 1 and 2 (except Hg).

Properties of Metals 1. Good Conductors of Electricity: 1. Electricity is the flow of electrons. Metals tend to release electrons to become positive ions. Therefore, metals are excellent conductors of electricity, because it has its own flow of electrons.
2. 2. Good Conductors of Heat: This is also explained by the flow of electrons in metals. As you heat one solid, its atoms vibrate more vigorously, but the free electrons allow the thermal energy of heat to be transferred easily. 3. 3. High Density and High Melting Point: The ions in a metal are usually packed closely together, lining up next to each other, leaving no gaps, this explains the high density of most metals. It also takes a lot of energy to separate this packed atoms, which explains the high melting point.
