Metals and Acids

Elements to the left of the periodic table's 'stepped line,' known for conducting electricity and heat.

A corrosive solution with a pH less than 7.

Potassium, sodium, lithium, and calcium.

Fizzing/bubbling, metal dissolving, and a temperature increase.

Metal + Acid → Salt + Hydrogen

A reaction where a substance combines with oxygen.

A reaction where a more reactive element displaces a less reactive one from a compound.

When iron reacts with oxygen and water to form iron oxide (rust).

A compound in the Earth's crust that contains a metal.

1. Use a lit splint.
2. A 'squeaky pop' indicates hydrogen.

A substance made of two or more substances that are physically combined but not chemically bonded.

A liquid or gas that dissolves a solute.

The substance that dissolves in a solvent to form a solution.

A solution in which no more solute can dissolve at a specific temperature.

The process of a liquid changing into a gas.

Metals are on the left, non-metals on the right, divided by a 'stepped line'.

Poor conductors, brittle, can be solids, liquids, or gases, and have a dull appearance.

Good conductors, ductile, malleable, shiny, usually solids with high melting/boiling points.

A vertical column in the periodic table.

A horizontal row in the periodic table.

Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs).

They become MORE reactive as you go down the group.

The elements get LESS reactive as you descend the group.

Changing directly from a solid to a gas without becoming a liquid.
