MIXTURES

Composition is variable.

Composition is in fixed proportions

Diatomic Element

-Found only combined in nature with itself.-7 diatomic elements. “BrINClHOF”

Br2 I2 N2 Cl2 H2 O2 F2

Monatomic element

-Found alone in nature.-Stable and inert (unreactive).

SubstancesElements : made of ONE TYPE of atom with their own unique properties.

PropertiesElements CANNOT be broken down chemically or physically.

Allotrope: two forms of the same element with different physical and chemical properties.

Allotropes have a different structural arrangement of atoms.

Ex: Diamond vs. Graphite

SubstancesCompounds: two or more different types of atoms CHEMICALLY COMBINED (bonded) in a fixed proportion.

PropertiesCompounds CAN BE broken DOWN with a chemical reaction

Ternary Compound3 or more different types of atoms chemically bonded.

Examples:

Binary Compound2 different types of atoms chemically bonded.

Compounds

Sodium metal + Chlorine gas Sodium chloride

When a compound forms, the reactants LOSE their original properties and form NEW chemical properties.

Therefore forming a compound is a CHEMICAL CHANGE.
