Metals – 16 - 2

1. What is a metal?
    A. Classify a metal –
        1. hardness, shininess, malleability, ductility
        2. ex. Silver (Ag) – shininess; copper (Cu) – malleability & ductility
2. Chemical properties –
    A. Wide range
    1. reactivity –
        i. speed at which an element reacts or combines
        ii. ex. Sodium (Na) & potassium (K)
    2. corrosion –
        i. wearing away
