How many different atoms are there?

Answer 1

Let's do the math.

There are currently about 120 known chemical elements. On average, each element has around three isotopes (where the nucleus has the same number of protons, but a different number of neutrons).

So a quick and dirty number would be that there are around 300-350 unique atomic nuclei. Or possibly twice that, if you consider the antimatter versions of each.

Answer 2

there are about 100 types of atoms as there are only about a 100 known elements! scientists however can only use 25 of them.

there are 92 different types of atom found naturally on earth. your body is made up of just 26 of these!

Answer 3

There are 118 different types of atoms because there are 118 elements on the Periodic Table of elements and each element is made of one type of atom like hydrogen is made of only hydrogen atoms but it has 1 atom in it and irin is made of 26 atoms tha are all iron atoms

Answer 4

Depends on the type of element. in one molecule of water, represented by H2O, there are three atoms, two hydrogen and one oxygen. In H2O2 (hydrogen peroxide) there are four atoms, two hydrogen and two oxygen. The subscripts (small number underneath the letters) tell you how many atoms there are. If there is no subscript, it is understood that there is only one atom.

There are 118 elements, though only 80 of these have stable isotopes and 26 are man made

Answer 6

The question is too vague to answer. All atoms of the same element have the same number of protons (if they had a different number of protons, they'd be a different element). However, they don't have to have the same number of neutrons, and the number of stable isotopes of an element vary depending on what the element is (some elements even have NO stable isotopes; depending on what theory you believe, it's possible that over the very long term no elements are stable... it is, however, true that we don't know of any stable isotopes for elements of higher Z than lead, and it's at least theoretically possible that the "stable" isotopes of lead are actually radioactive with extremely long half-lives).

Answer 7

An element is ONE kind of atoms in a (poly-atomic) molecule, or it is one atom itself (mono-atomic element)

Answer 8

Today are known approx. 3 100 isotopes and isomers.

Answer 9

There are 110 atoms!!!!

Answer 10

120 different kinds of atoms
