how do oxygen atoms compare to the atoms in another element, hydrogen?

Answer 1

Atoms are particles of elements, substances that could not be broken down further. In examining atomic structure though, we have to clarify this statement. An atom cannot be broken down further without changing the chemical nature of the substance. For example, if you have 1 ton, 1 gram or 1 atom of oxygen, all of these units have the same properties. We can break down the atom of oxygen into smaller particles, however, when we do the atom looses its chemical properties. For example, if you have 100 watches, or one watch, they all behave like watches and tell time. You can dismantle one of the watches: take the back off, take the batteries out, peer inside and pull things out. However, now the watch no longer behaves like a watch.

The atom , made up of one proton and one electron, is called hydrogen (the abbreviation for hydrogen is H). The proton and electron stay together because just like two magnets, the opposite electrical charges attract each other. What keeps the two from crashing into each other? The particles in an atom are not still. The electron is constantly spinning around the center of the atom (called the nucleus). The centrigugal force of the spinning electron keeps the two particles from coming into contact with each other much as the earth's rotation keeps it from plunging into the sun.



Comparison

Oxygen:

Oxygen gas was discovered by Swedish pharmacist, Karl Scheele in 1771. Oxygen is prepared in fundamental chemistry using the same process Scheele, Priestley and Lavoisier (who named the element) employed. Comprising 87 percent of the oceans, one fifth of the atmosphere and six out of ten atoms on the crust, oxygen is the most abundant element on the surface of the earth. many compounds are studied in all of our chemistry classes.
