Rutherford
john dalton atom is from bigger atom into smallest atom can broken it into smallest piece / part same too atom
particle accelerator
We need to know the number of protons in the atomic nucleus.
Electrons are found in the electron cloud surrounding the nucleus of an atom. They move rapidly within this region, occupying various energy levels based on the atom's structure.
You find experiments while doing the Creature of Frekenstrain quest. There is a portion where you are asked to go underground, and you will find experiments there.
We find the positively charged protons and the uncharged neutrons tightly bound in the nucleus of the atom. The negatively charged electrons are in the electron cloud around the nucleus. Other questions speak to the structure of the atom, and some are linked below.
You can find experiments on the Internet, in labs, science fairs, almost any place with science involved .
You can find a proton (+) in the center of a atom.
you can find the neutron in the center of an atom.
You can find a picture of a Bohr Rutherford diagram for a carbon atom by doing an image search on a search engine like Google or by checking science textbooks or educational websites that cover atomic structure.
It was the investigator J. J. Thomson who did experiments with an early cathode ray tube. You'll find a link below.
Draw the structure based on the name. Then count the number of times each atom appears in the structure. Alternately, you can determine the formula from the structure - and then count all atoms of each type.
