1

What is an element???

A substance in which cannot be separated into simpler substances as a result of any chemical change.

If broken down further it will not have the same properties.

Different elements are classified based on different physical properties.

2

Atoms
Molecule
Ions
???

ATOMS: smallest particle of an element that still retains the chemical identity of the element.made up of protons, electrons, neutrons.

MOLECULE: a cluster of two or more atoms held together with a covalent bond.

IONS: an atom or a group of atoms that has gained or lost electrons to become positive or negative charged.

3

What is a particle and a phase???

Particle: a General way to say a small bit of matter such as a atom, molecule, or an ion.

Phase: any part of a system which is uniform in both composition and properties.

4

What are the properties of matter???

Elements,
Compounds,
Mixtures.

5

What is a pure substance???

A substance that has an unchangeable composition.

6

What is a compound???

A combination of elements that has a different set of properties than the elements it’s composed of.

NaCl

7

What is a mixture???

A combination of two or more substances.

There are two types heterogenous and homogenous.

8

What is heterogenous

Mixture with a varying composition, and more than one phase present. (Salt and pepper, trail mix, macaroni salad)

9

What is homogenous???

Mixture with uniform composition throughout, only one phase present.

(Boiling point, density, etc....)

10

What is a solution???

A example of a homogenous mixture, but not at solutions are solid dissolved in a liquid. Mostly the ones we have talked about are!

11

What are the two components of a solution???

SOLUTE: the component which exists in smaller quantity.

SOLVENT: the component which exists in larger quantity.


When water is in a solution it is always a SOLVENT, Which is a aqueous solution.
