What is Chemistry?

Chemistry is the study of the composition of matter and the changes it undergoes

What is matter?

Matter is something that has mass and takes up space (volume)

Technology of Chemistry

This is the skills, processes, and equipment required to make useful products or to perform useful tasks

Pure Chemistry

Refers to pure research; there is no true task in mind besides learning

Applied Chemistry

Using scientific knowledge to solve a human problem. Ex. Pharmaceutical research

Organic Chemistry

The study of all chemicals involving carbon

Inorganic Chemistry

The study of chemicals that don't contain carbon, most of these are non living. Ex. Rocks


This study of Chemistry focuses on the processes that take place in living things. Ex. Muscle contraction and digestion

Analytical Chemistry

This study focuses on the composition of matter

How much lead is in water?

Physical Chemistry

This part of Chemistry deals with the mechanism, rate and the energy transfer that occurs when matter undergoes change

Pure Substance

A pure substance has a definite and uniform composition


An element is a pure substance that are composed entirely of one kind atom. They cannot be broken down by physical or chemical means.


Made up of two or more kinds of atoms bonded together in a fixed proportion. They can be broken down into elements by chemical means.


NO BONDING! Just a physical blend of two or more components

Homogeneous Mixture

This type of mixture has just one phase, also known as a solution, it has a uniform composition and can be separated physically

Extensive Properties

These properties have to do with the amount in the sample of matter given, when the sample size changes, these properties change as well. These properties have to do with mass, weight, volume, and length

Intensive Properties

These properties have nothing to do with the sample size and everything to do with the type of sample given. These could be the lustre, color, density, malleability, ductility, hardness, melting/boiling point, etc.

Physical Property

This type of property can be measured or observed with your 5 senses. Intensive and extensive properties are considered this


Has a definite shape and volume because the particles are tightly packed together in an orderly pattern


Has a definite volume, but takes the shape of its container because the particles aren't packed as close together and are able to move slightly


Has no definite shape or volume, the particles are much further away than those of a liquid


The gaseous state of a substance that is usually a solid or liquid at room temperature

Physical Change

BONDS AREN'T BEING BROKEN! Some properties of the material changes, but the composition of the material does not. Ex. Cut, grind, melt, freeze, condense, etc.

Chemical Change

BONDS ARE BROKEN! Also known as a chemical reaction, this change produces matter with a different composition (new arrangement, new bonds, new properties). In other words, something new is produced

Chemical Equation

Uses the following format: REACTANTS➡PRODUCTS

The Law of Conservation of Mass

This states that during a chemical reaction, the mass of the products always has the same mass as the reactants, in other words, mass is never gained or lost

Chemical Symbols

One or two letter symbols that represent each element

Chemical Formulas

Represent compounds, they indicate the types and amounts of atoms in a compound



Triad Organization

J.W Dobereiner published a table in which elements were arranged into triads with similar properties

Period Table (Dimitri Mendeleev)

Arranged into groups based on repeating properties, he arranged his table in order of increasing atomic mass.

Modern Periodic Table

In this table, elements are arranged according to increasing atomic number

Periodic Law

When arranged according to increasing atomic number, there is periodic repetition of physical and chemical properties. These properties repeat from left to right across each period


80% of the periodic table, they are good conductors of heat and electricity, high lustre, solid at room temperature (exception to Hg), ductile and malleable

Non Metals

Most are gases at room temperature, they have varying properties... so many to list


These have properties similar of both metals and non metals
