What are some major contributions or positive impacts that the discovery of atoms has made?
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.
What else can I help you with?
Which particles in atoms have a positive charge?
Protons have a positive charge in atoms.
Describe the discovery that demonstrate for the first time that atoms are not the smallest particles of matter?
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.
Can electrons be positive?
No, electrons cannot be positive. They are negatively charged particles found in atoms.
Is the nuclei of atoms electrically positive?
Yes, the nuclei of atoms are electrically positive because they contain protons, which have a positive charge. The positive charge of the protons in the nucleus is balanced by the negative charge of the electrons orbiting around the nucleus.
What were JJ Thomson's discovery?
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.
How did discovery of electrons show that there are also positively charged parts of the 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.
Which particles in atoms have a positive charge?
Protons have a positive charge in atoms.
What is the contributions of Democritus's in physics?
atoms
Do neutral atoms stick to positive atoms?
By extreme heat and pressure, neutral atoms stick to positive atoms. Such as in Nuclear fission/ fusion.
Who discovered the modern day discovery regarding Atoms?
The modern understanding of atoms was significantly advanced by John Dalton in the early 19th century, who proposed the atomic theory, suggesting that matter is composed of indivisible atoms. Later, J.J. Thomson discovered the electron in 1897, revealing that atoms are not indivisible but contain smaller particles. This was further refined by Ernest Rutherford's gold foil experiment in 1909, which led to the discovery of the atomic nucleus. Together, these contributions laid the foundation for the contemporary atomic model.
What is an atom that has a net positive or negative electric charge?
Positive atoms: cations. Negative atoms: anions
What part of daltons theory was modified after discovery of isotopes?
Atoms may not be changed into other atoms.
What part of daltons theory was modified after the discovery of isotope?
Atoms may not be changed into other atoms.
What are atoms OR groups of atoms with a positive OR negative charge?
a zewithalarion shows poth positive and negative; go figure...
What did Henry moseley discover about the atom?
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.
What was ernest rutherfords discovery?
Rutherford found that atoms have a nucleus
What discovery demostrated that atoms are mostly empty space?
bohr
