(Actually, the O-shell could theoretically fit 50 electrons, but there is no known element with this many electrons.) How atoms become ionized Star-forming regions in space like the Orion Nebula pictured here are home to budding stars. Ultraviolet light from these young stars carves a cavity ...
How many atoms are in a human? It is hard to grasp just how small the atoms that make up your body are until you take a look at the sheer number of them. An adult is made up of around7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms. ...
Atoms are in your body, the chair you are sitting in, your desk and even in the air. Learn about the particles that make the universe possible.
How Many Protons, Neutrons, and Electrons Are in Common Elements? 1. What elements are in these common items? 2. List the three subatomic particles that make up atoms. Give the mass and charge of each one. 3. Fill in the information for elements on your chart. Record the number of pro...
Isotopes. Every atom is a chemical element, like hydrogen, iron or chlorine. ... Radioactive. Some atoms have too many neutrons in the nucleus, which makes them unstable. ... Ions. ... Antimatter. Are humans made of atoms? About 99 percent of your body is made upof atoms of hydrogen...
The steps of an MRI © 2008 HowStuffWorks.com When patients slide into an MRI machine, they take with them the billions of atoms that make up the human body. For the purposes of an MRI scan, we're only concerned with the hydrogen atom, which is abundant since the body is mostly m...
Atomic number:The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines what element it is and determines its chemical behavior. For example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalw...
That's how many joules (the standard measurement of energy) you'd get from a kilogram of mass. In theory, if you could turn about seven billion hydrogen atoms completely to energy, you'd get about one joule (that's about as much energy as a 10-watt lightbulb consumes in a tenth of...
We can see which atoms for a certain molecule. Also, we can determine the number of each atom. Most interesting, by adding up the mass of each atom we can get the mass of the molecule.Answer and Explanation: A mole of a compound or atom or element of whatever you choose implies...
How many chemical elements is hair made of? What determines what kind of chemical element an atom is? How is an atom different from an element? What is formed when atoms form covalent bonds? What does each different element on the periodic table of elements represent?
