All matter is made of tiny particles called atoms. An ______ is the smallest particle of an element that still has the properties of that element. atoms. atom Recognize that matter is composed of extremely small particles called atoms, which are too small to be seen with a classroom microscope. Atoms have all the properties of matter in that all atoms have mass and occupy space. Atoms are the smallest part of an element that has chemical properties of the element. All atoms of the same element have the same properties. Iron atoms are different from carbon atoms or from any other elements.

Atoms are too small to see with the naked eye or most microscopes. Recognize that matter is composed of extremely small particles called atoms, which are too small to be seen with a classroom microscope. Atoms are the smallest part of an element that has chemical properties of the element. All atoms of the same element have the same properties. Iron atoms are different from carbon atoms or from any other elements.

The _________ is in the center of the atom like the _____ is in the center of the solar system. The __________ orbit around the nucleus like the ________ around the sun. nucleus sun electrons planets Extension Not in standards, but we quickly go over this comparison

An _______ is a substance that is made of only one kind of atom. element Recognize there are more than 100 elements that combine in a multitude of ways that make up all of the living and non-living things that we encounter. Atoms are the smallest part of an element that has chemical properties of the element. All atoms of the same element have the same properties. Iron atoms are different from carbon atoms or from any other elements.

All the atoms of an element have the same properties (they are alike in every way). For example, all iron atoms have the same mass and occupy the same space as all other iron atoms. All atoms of the same element have the same properties. Iron atoms are different from carbon atoms or from any other elements.

All carbon atoms have the same mass and occupy the same space (volume) as all other carbon atoms. All atoms of the same element have the same properties. Iron atoms are different from carbon atoms or from any other elements. Carbon atoms on Earth and Mars are exactly the same!

There are about 117 known elements. Recognize there are more than 100 elements that combine in a multitude of ways that make up all of the living and non-living things that we encounter.

Recognize there are more than 100 elements that combine in a multitude of ways that make up all of the living and non-living things that we encounter. These 117 elements combine in a huge variety of ways to make up ALL living and non-living things!
