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. See morenuclear power pictures. It has been said that during the 20th century, man harnessed the power of the atom. We madeatomic bombsand generatedelectricitybynuclear power. We even split the...
How many valence electrons does Hydrogen have? How many bonds does selenium have with hydrogen? How many atoms can be on one element? How many atoms are in oxygen? How do hydrogen bonds between water molecules occur? How many atoms does glucose have? a) How many molecules are there in 17...
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.

Stable. Most atoms are stable. ... 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. ...
The chemical formula is the formula of a compound in which: 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....
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...
To do this, look up atomic masses on the periodic table and use the formula mass to know how many atoms of each element are in a compound. Remember, subscripts in a formula indicate the number of atoms. If there is no subscript, it means there is only one atom of that element in th...
