Living things, for example, are mostly made from the atoms carbon, hydrogen, and oxygen. These are just three of over 100 chemical elements that scientists have discovered. Other elements include metals such as copper, tin, iron and gold, and gases like hydrogen and helium. You can make ...
Define the atomic mass of an atom. What are two things that make up an atom? What one factor identifies an atom as a specific element? What makes the carbon atom uniquely suited to building large molecules? What is it that essentially determines the size of an atom?
Atoms are made up of a nucleus, protons and electrons. Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be ...
Atoms are the basic units of matter. Everything in the universe apart from energy is made of matter therefore atoms make up everything in the universe, according toNorthwestern University. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were ...
Are cells made up of atoms? If so, what differentiates us from non-living things? Define cell. What are the two main tenets of cell theory? What are some of the structures inside a cell that helps it to live to perform its role in an organism? What are the functions of the cytoskele...
the universe's fundamental forces — gravity, electromagnetism, and the strong and weak nuclear forces — breaking or ripping apart everything that is currently bound together by those forces, be it galaxies, planets, or people, even the protons and neutrons that make up atoms. ...
The parts of the electromagnetic spectrum which are used by 5G communications - the portion from 22Ghz to 86GHz - are fundamentally non-ionising and incapable of breaking molecular bonds, knocking off electrons from atoms for instance, and causing the molecule to have an electric charge, which ...
What 2 things are the Sun mostly made of? The Sun is a huge, glowing sphere of hot gas. Most of this gas ishydrogen(about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon...

All glass is non-uniform at the atomic level. However, for transparent glass, this does not greatly affect the index of refraction when averaged over a wavelength-sized region. There are many, many atoms in such a region. The best glass is phenomenally transparent. The glass used in undersea...
