O is always made of 2 hydrogen and 1 oxygen. Atoms consist of a positively charged nucleus made up of protons and neutrons that is surrounded by a negatively charged electron cloud. All matter is composed of tiny indivisible particles called atoms 2.

LODP results from the fact that a given chemical compound is always composed of the same combination of atoms. Atoms of a given element are identical in size mass and other properties. The Building Blocks of Matter Section.

Constant composition implies constant properties. You will learn what makes atoms th. The Building Blocks of Matter.

The Development of a New Atomic Model 1. Atoms of a given element are identical in size mass and other properties. Explain how electrons occupy electron shells and their contribution to an.

They are all made of these same basic parts they differ in how many of them they have. List the five main points of Daltons atomic theory. So the mass ratio.

Explain how an atom can exist in this state. However even the atom can be broken into smaller pieces called quarks. Matter changes when reacted or changed.

The mass of the reactants is the same as the mass of the products. The Stucture of the Atoms 1. The mass of all reactants are changed during a physical or chemical change.

Atoms of different elements combine in simple-whole number ratios to form chemical compounds In chemical reactions atoms are combined separated or rearranged. Atoms of different elements differ in size mass and other properties. Atoms are the smallest particle of pure matter that can exist on its own and is stable there are smaller bits but they go around causing trouble as they arent stable.

Atoms cannot be subdivided created or destroyed. Chapter 3 test - Atoms. One of the main challenges of this introduction and this is true at all levels is that learners are easily confused by the terminology.
