What Are Atoms?Introduces the concept of atoms and molecules, and includes protons, neutrons, and electrons.Lisa TrumbauerLinda Bullock
What are atoms made of?Atoms:Atoms are units of matter that possess chemical and physical properties capable of classifying them as elements. These are considered the basic building blocks of the universe because atoms form molecules which comprise all the different kinds of matter we see....
What Are Atoms? You can't see atoms, but they make up everything around you: your chair, your desk, the birds outside, even you!Atomsare the foundation of matter, which is everything that makes up the universe around us. Each kind of atom makes up a pure substance called an element...
Atoms are a bit like people: they usually prefer company to being alone. A lot of atoms prefer to join up with other atoms because they're more stable that way. So hydrogen atoms don't exist by themselves: instead, they pair up to make what is called a molecule of hydrogen. A molecu...
All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportion of oxygen atoms. Although the st...
Here are some atom examples: Neon (Ne) Hydrogen (H) Argon (Ar) Iron (Fe) Calcium (Ca) Deuterium, an isotope of hydrogen that has one proton and one neutron Plutonium (Pu) F-, a fluorine anion Protium,an isotope of hydrogen Atoms Versus Molecules ...
What are atoms most made of? Every atom is composed of anucleusand one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons. More than 99.94% of an atom's mass is in ...

If any matter is smaller or larger than an atom, it is not an atom. Molecules and compounds may contain atoms, but they are not atoms themselves. Some examples of molecules and compounds are salt water (NaCl) and ethanol. Electrically charged atoms that conduct electricity are called ions, ...
Every element is made of atoms—piles of paper clips. All atoms of any element are the same—all the paper clips in the pile are the same size and color. Atoms of different elements are different in size and properties—like different sizes and colors of paper clips. Atoms of different ...
