, double the number of atoms, because there are 2 atoms per molecule. Remember, one mole of something is 6.022 X 1023 of whatever it is. If it is molecules, it’s 6.022 X 1023 of them.
How many atoms are in 3H2O?
For example, 3H2O means there are 3 molecules of H2O. See Fig. 2 for the pictorial representation of 3H2O. As you can see, there are 3 Oxygen atoms and 6 oxygen atoms .
How many atoms are in an element?
An atom is an element. The two words are synonymous, so if you’re looking for the number of atoms in an element, the answer is always one , and only one.
Is oxygen atom bigger than hydrogen atoms?
The hydrogen atom has one electron, whereas oxygen has eight, so the oxygen atom is much larger than the hydrogen . The water molecule looks a little like Mickey Mouse, because the angle between the two hydrogen atoms where they connect with the oxygen atom is about 104 degrees.

Can atoms be destroyed?
No atoms are destroyed or created . The bottom line is: Matter cycles through the universe in many different forms. In any physical or chemical change, matter doesn’t appear or disappear. Atoms created in the stars (a very, very long time ago) make up every living and nonliving thing on Earth—even you.
How long do atoms last?
For carbon-14, this number is 5,730 years . For different radioactive atoms, this number can be anywhere from a tiny fraction of a second to minutes, hours, days, or even millions of years. But, in all these cases, the point of the decay is to reach a type of atom that is stable.
