In this video Paul Andersen explains how elements and molecules are made of atoms. In a pure sample of a pure substance the average mass remains the same. If more than one atom is found in a molecule the ration of average masses...

In this video, we're going to talk about the difference between elements and compounds. We'll cover the basics of chemistry, and explain the differences between elements and compounds.

This video is a lesson on how to represent elements and compounds in terms of the atoms they can take. The video covers the definition of an element, the periodic table, chemical symbols, and formulas. It also explains how compounds are...

This video provides an overview of the structure and notation of atoms, including the positively charged nucleus, negatively charged electrons, protons, neutrons, and the arrangement of electrons in energy levels. It also explains how to...

This video discusses the electronic configuration of atoms and ions, and how the positioning of elements in the periodic table affects their electronic structure. It further discusses the electronic configuration of different elements...

This week's SciShow news brings you discoveries involving two of the most exotic substances on Earth - the world's rarest element and the world's oldest water. Two great tastes that taste great together? Stay tuned to find out.

The video explains how the periodic table is arranged and how this arrangement highlights patterns in the chemical properties of elements. It covers the order of elements based on their atomic number, their placement in groups based on...

Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about the elements.

A video entitled “Understanding the Atom” which introduces the atom and atomic structure before discussing how atoms are studied and classified.

The Periodic Table: Atomic Number examines the Periodic Table of Elements and uses the atomic number to identify the number of protons, neutrons, and electrons in a given element.

In this video, we'll be talking about how to determine the number of protons, neutrons, and electrons in an ion. We'll be using the periodic table to help us out, so don't miss it!

The first stars turned all the neutral hydrogen in the universe back into ions, created a bunch of new elements, and just generally made a mess. But without them, you wouldn’t be here.

Learn the basics about the atom, whilst learning about properties of matter. Atoms are the small bits that make up all the matter in the world around us. There are around one hundred different sorts of atom, from the lightest, hydrogen...

In this part 2, learn the basics about the atom, particularly about isotopes, whilst learning about properties of matter. Learn the basics about the atom, whilst learning about properties of matter. Atoms are the small bits that make up...

NOTE: animation error at 2:40 - the periodic table is supposed to be twisted clockwise, and not like it is shown in the video. The twisting enables the element Cs to appear on the extreme left and the element F to appear on the right. In...

Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains...

In this video, we learn about atoms and their subatomic particles - protons, neutrons, and electrons. We also explore how these particles combine to form different elements and how the periodic table is structured. The video provides a...

Learn the basics about Atomic Mass Units. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems. Find out more in this video!

In this video, the smallest particle of a chemical element, the atom, is discussed along with its various representations. The video provides information on the structure of atoms and their various components, including the nucleus,...
