Chemistry, Part 1: Atoms Science With Mr. Comans

In this Powerpoint you will find: Structure of Atoms What are atoms? What are the particles in atoms? What is an electron cloud? How do the particles’ masses compare? This information goes along with pages 42-45 in the Green Science Explorer book.

In This Powerpoint: Atoms and Elements What is an atomic number? What are isotopes? What is a mass number? This information goes along with page 46 in the Green Science Explorer book.

But first…

Protons, neutrons, and electrons

Structure of an Atom What is the difference between molecules, elements, and compounds?

Structure of an Atom Nucleus-the central part of the atom, is made from protons (+) and neutrons (0). The electrons (-) are found in a cloud around the nucleus.

Structure of an Atom What particles make up nucleus?

Structure of an Atom If a proton had the mass of a baseball… …an electron would be the mass of one grain of rice.
