I need a site that will tell me the number of electrons, protons, and nuetrons in any element.?

Question

I really need to know the number of electron, protons, and nuetrons of every element. Or if I could find a picture that tells how to find that from the element's square on the periodic table, that would be super, too. Please include links. I'll love you for it.

Answer 1

Individual elements have things called isotopes... The same atom with different numbers of protons and neutrons and electrons. Take Hydrogen: One proton, one electron. If a Hydrogen atom has one proton, one neutron and one electron, its still hydrogen but has a different atomic weight. (actually they named that isotope deuterium) More complex atoms further down the periodic table have many isotopes, some stable, some radioactive. Some bond easily, some degenerate. The information in the periodic square is for the most commonly found isotope of each element. hope this helps... TITO's link is awesome... and on that page there is another link to list all the isotopes of each element.... wow!

Answer 2

mushroomhead is right- its on the periodic table- number of electrons is directly the same as its position on the chart electronics are always the number as protons and the left over amount is nuetrons if you science teacher didn't tell you that I'd wonder how good a teacher you have.

Answer 3

Some of what you're looking for. Click on each element for more detail.

Answer 4

Stupid it says on every periodic table, if yur not smart enough to know that then, good luck w/ th e res of the year

Answer 5

Have you thought of getting a periodic table?

Answer 6

OMG if they made a chart with that information that would be awesome!
