Characteristics of Metals

Metals have a ——— melting and boiling point

• low

• high

metal + steam =

How does potassium react with dilute acids

• extremely violently

• does not react

• reacts very slowly

reaction of silver with water

• reacts very slowly with cold water

• reacts vigorously with cold water

• does not reach with water or steam

metal oxide + oxygen =

• salt + carbon dioxide

• acid+ water

• salt+ water

• hydrogen

metal + water =

• metal oxide

• metal hydroxide + hydrogen

• salt + hydrogen

2Na+ 2HCL ——> 2NaCl + H2 is an example of what type of reaction

• metal + oxygen —-> metal oxide

• metal + acid —> salt + hydrogen

• metal + water -> metal hydroxide + hydrogen
