Particle Nature of Matter, Atomic Structure and Periodic Table Introduction and Focus Question: Have you ever wondered what things are made of? Have you asked yourself, “Do I really need vitamins, minerals and nutrients? Have you thought of checking the nutritive value of the fool products that you are buying? The building block of matter is the atom. Its properties and behavior make matter useful. Its study makes science dynamic and productive. The existence of the atom marks the importance of every material in our environment. In this module you will discover the compositions of matter. Always bear this question in your mind as you go through the activities: How does the properties of matter influences the water system in the Philippines? You can use your textbook as guide for answering the activities: Science Link 8 pages 233-254 Or visit our website: www.camarinesnortecollegejhs.com Unit Concept Map Topics: You’ll learn to… The Particle ✓ describe the different properties of matter Nature of Matter ✓ explain the properties of solids, liquids, and gases based on the particle nature of matter.

For this week, you will surely accomplish the targets of your learning below. Don’t forget to monitor your accomplishment on the following learning targets: ✓ You can identify the group, period, orbitals and the types of each element using periodic table. ✓ You use the periodic table to predict the chemical behavior of an element. Key Concepts: Groups, or vertical columns, elements in a group are different but have similar chemical and physical properties because they have the same number of outer electrons. For instance, the noble gasses have their outermost orbit filled and therefore atoms from this family do not bond with other atoms. Period, or horizontal rows. Along a period, a gradual change in chemical properties occurs from one element to another. Changes in the properties occur because the number of protons and electrons increases from left to right across a period or row. The increase in number of electrons is important because the outer electrons determine the element’s chemical properties. p- block d- block SCIENCE 8// MATTER//QUARTER 3// S.Y.2021-2022 8
