How did the discovery of radioactivity contradict Dalton's atomic theory?
radioactivity proves that there are smaller particles in an atom that makes it up, they are proton, neutron, and electron. Dalton's atomic theory clearly states that the atom is the simplest particle. Radioactivity contradicts Dalton's theory since it proves that there are particles which are simpler than the atom.
Is radioactive acidic?
No, radioactivity refers to the emission of particles or energy from the nucleus of an atom, while acidity refers to the concentration of hydrogen ions in a solution. These are two separate properties and being radioactive does not make a substance acidic.
What is a sentence for radioactivity?
Chernobyl is well-known for it's dangerously high radioactivity levels.
Compared to an atom of C-12 an atom of C-14 has?
two more neutrons in its nucleus, making it slightly more massive. This difference in neutron number also contributes to C-14's radioactivity, as it undergoes beta decay to turn into N-14.
What is the order of magnitude of the radius of an atom?
The order of magnitude of the radius of an atom is Angstrom Units (10-10 m)
How does an atom's electrons affect its radioactivity?
An atom's electrons typically do not directly affect its radioactivity. Radioactivity is mainly determined by the nucleus of the atom, which contains protons and neutrons. The arrangement of electrons around the nucleus may play a role in the stability of the nucleus, but it is the composition of the nucleus itself that primarily determines an atom's radioactivity.
What is it called when an atom decays and become another element?
Radioactivity
How is radioactivity formed?
Radioactivity occurs when some of the binding energy in an atom becomes converted into kinetic energy, resulting in the expulsion of some of the particles of the atom. And generally some energy as well.
Spontaneous emission of radiation from an atom?
This physical phenomenon is called radioactivity.
What is the stability of an atom determined?
Radioactivity is identified with radiation detection instruments.
Who showed that radioactivity is caused by the breakdown of one atom into another?
Ernest Rutherford
Who named the process by which materials give off energy of an uranium atom radioactivity?
The process by which materials give off energy from a uranium atom was named radioactivity by Marie Curie in the early 20th century. She discovered that certain elements, like uranium, emit radiation spontaneously.
How is radio activity related to the atom?
radioactivity is produced by state changes in the protons & neutrons within the nucleus of the atom and their binding forces.
What discovery rejects the idea that atom is indestructible?
Its RADIOACTIVITY!! That was the first discovery that rejects the idea that the atom is indestructible
When a uranium atom 92u235 decays radioactivity to became protactinium 91u231 the radiation emitted are?
entropy
What the meaning of radiocative?
Radioactivity results from unstable elements. This means the amount of protons in the nucleus of the atom is not equal to the amount of electrons in the outer shells of the atom.
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
