One of the most major positive effects of the discovery of the atom is that by splitting atoms of radium in a nuclear power plant, we can gain a lot of energy. However, the waste produced in this process is very toxic and can damage us badly.......... Also, the nuclear bombs produced using these theories are very deadly.
J.J. Thompson worked to develop the atomic theory. He discovered that atoms have separate negative and positive material. Before him, it was widely believed that atoms were just spheres of matter.
electrons
The discovery of the subatomic particles demonstrated for the first time that atoms are not the smallest particles of matter. Electron was the first subatomic particle discovered by J.J. Thomson.
The nucleus of an atom is positively charged.

atoms
The discovery of the electron proved the positive charge of the atom when sending an electric spark across an air gap from one electrode to another, called the photoelectric effect.
By extreme heat and pressure, neutral atoms stick to positive atoms. Such as in Nuclear fission/ fusion.
Positive atoms: cations. Negative atoms: anions
These ideas are:· "All atoms of a given element are identical" : discovery of isotopes.· "A given compound always has the same relative numbers of types of atoms" : discovery of nonstoichiometric compounds.
Atoms may not be changed into other atoms.

a zewithalarion shows poth positive and negative; go figure...
He found that atoms of each element contain a unique positive charge in their nucleus. This discovery helped to solve the mystery of what makes the atoms of one element different from those of another: An atom's identity comes from the number of protons in its nucleus.
