Topic 5 (5.4 & 5.5)

An atom that has a positive or negative charge because it lost or gained electrons.

• Proton
• Molecule
• Ion

The connection between two ions with opposite charges (positive and negative). Electrons are transferred between the ions.

• Ionic bond
• Covalent bond
• Hydrogen bond

A type of covalent bond where electrons are shared equally.

• Polar covalent bond
• Ionic bond
• Nonpolar covalent bond

Type of covalent bond where electrons are shared unequally.

• Polar covalent bond
• Nonpolar covalent bond
• Ionic bond

This substance tastes sour, can react to metals, and turns blue litmus paper red.

• The substance is likely to be an acid.
• The substance is likely to be a neutral solution.
• The substance is likely to be a base.

This substance tastes bitter, feels slippery, and turns red litmus paper blue.

• base

• salt
• acid

This is created when an acid and base neutralize. It is an ionic compound.

• Sugar
• Vinegar
• Salt

A bond when two or more atoms share electrons.

• Ionic bond
• Covalent bond
• Hydrogen bond

When a base and an acid react with each other.

• They form a metal and a non-metal.
• They form a salt and water.
• They form a gas and a solid.

Neutralization is when

• an acid and base react with each other

• an ionic bond and covalent bond react with each other

• an ion and a molecule react with each other
