1. The atoms in all objects are the same.
2. You cannot always tell by an object’s appearance whether it is made of more than one type of atom.
Do you agree or disagree?

• What is a substance?• How do atoms of different elements
differ?• How do mixtures differ from
substances?• How can you classify matter?
Key Concepts

Matter is anything that has mass and takes up space.
Everything you can see is matter, but some things you cannot see, like air, are also matter.
An atom is a small particle that is a building block of matter.

Atoms• At the center of an atom is the nucleus.
• Protons, which have a positive charge, and neutrons, which have no charge (or a neutral charge), make up the nucleus.

Atoms Electrons are negatively
charged particles that move quickly throughout the area around the nucleus called the electron cloud.
Not all atoms have the same number of protons, neutrons, and electrons.
Atoms that have different numbers of protons have different properties.

There are two main classifications of matter:
• -Substances Mixtures
• A substance is matter with a composition that is always the same.
• Substances are always made up of one or more atoms in the same combinations.
• Two types of substances are elements and compounds

Element: substance that consists of just one type of atom
Because there are about 115 known elements, there are about 115 different types of atoms.
Each type of atom contains a different number of protons in its nucleus. The number of protons in an atom is the atomic number of the element

The atoms of most elements exist as individual atoms. For example a roll of pure aluminum foil
consists trillions of individual aluminum atoms
But the atoms of some elements exist in groups Oxygen atoms in the air naturally exist in
pairs Whether the atoms of an element exist
individually or in groups, each element contains only one type of atom. Therefore, its composition is always the same.

Each element on the periodic table consists of just one type of atom.

Compound: type of substance containing atoms of two or more different elements chemically bonded together.
The combination of symbols and numbers that represents a compound is called a chemical formula.
Compounds
![Page 19: 10-1 Classifying Matter 1. The atoms in all objects are the same. 2. You cannot always tell by an object’s appearance whether it is made of more than.](https://reader036.fdocuments.net/reader036/viewer/2022062519/5697bfe41a28abf838cb57fc/html5/thumbnails/19.jpg)
The combination of symbols and numbers that represents a compound is called a chemical formula.
![Page 20: 10-1 Classifying Matter 1. The atoms in all objects are the same. 2. You cannot always tell by an object’s appearance whether it is made of more than.](https://reader036.fdocuments.net/reader036/viewer/2022062519/5697bfe41a28abf838cb57fc/html5/thumbnails/20.jpg)
Chemical formulas show the different atoms that make up a compound, using their element symbols.
Chemical formulas also help explain how the atoms combine.
A compound often has different properties from the individual elements that compose it.

A mixture is matter that can vary in composition.
Mixtures are combinations of two or more substances that are physically blended together.
The amounts of the substances can vary in different parts of a mixture and from mixture to mixture.
Mixtures
![Page 22: 10-1 Classifying Matter 1. The atoms in all objects are the same. 2. You cannot always tell by an object’s appearance whether it is made of more than.](https://reader036.fdocuments.net/reader036/viewer/2022062519/5697bfe41a28abf838cb57fc/html5/thumbnails/22.jpg)
A heterogeneous mixture is a type
of mixture in which the individual substances are not evenly mixed.
Because the substances in a heterogeneous mixture are not evenly mixed, two sample of the same mixture can have different amounts of the substances.
Types of Mixtures

A homogeneous mixture is a type of mixture in which the individual substances are evenly mixed
In a homogeneous mixture, the particles of individual substances are so small and well-mixed that they are not visible, even with most high-powered microscopes.
Types of Mixtures

Make a list of 5 heterogeneous mixtures, and a list of 5 homogeneous mixtures
In your ISN

To dissolve means to form a solution by mixing evenly.
A homogeneous mixture is also known as a solution.

How do mixtures differ from substances?
In your ISN

The composition in a compound does not vary. Therefore, a chemical formula can be used to describe the compound.
Because composition in a mixture can vary, a chemical formula cannot be used to describe mixtures.
Compounds vs. Solutions

A substance has the same composition throughout.
A substance is either an element or a compound.

An atom is the smallest part of an element that has its properties . Atoms contain protons, neutrons, and electrons. The substances in a mixture are
not chemically combined. Mixtures can be either heterogeneous or homogeneous.
