Welcome to this worksheet on atomic structures and isotopes! In this worksheet, you will learn about the basic building blocks of matter - atoms. You will understand the structure of atoms, including the positively charged nucleus, and the negatively charged electrons that orbit around it. You will also learn about isotopes, which are atoms of the same element that have a different number of neutrons in their nuclei. This worksheet will provide a clear and concise overview of these concepts and will give you a chance to practice your knowledge through interactive questions and exercises. So, get ready to delve into the world of atomic structures and isotopes!

This is a precise laboratory experience where students will learn how to find out the density of liquids. Learning by Doing is the way.

Hello, teacher! Let me explain what I designed for you, here. This is a document where students can practice the specific and general properties of matter. Students will… Differentiate between specific and general properties of matter. Figure out two exercises about how to find out the density of a regular and irregular object (specific property). Create a mind map where they show what they know about the properties of matter. Learning by doing…

Teach the four periodic properties: atomic size/radius, electronegativity, electron affinity and ionization energy. This worksheet has definitions, illustrations with the tendency/trend in the periodic table and some exercises. It’s important to say that I decided to not include the answer, because students can access to this by buying it and sharing on the Internet and the worksheet will not be functional with the time if it occurs. My name is Raphael, a Biologist who like to create content to teach Science. Learning by doing is my way.
