Why is radioactivity unpredictable?
Radioactivity depends on subatomic processes, and those are inherently unpredictable. The "why" is difficult to answer; but it seems that's the way our Universe works. You can calculate probabilities only.
What fundamental force causes some form of radioactivity?
The fundamental force responsible for some forms of radioactivity is the weak nuclear force. This force is involved in processes such as beta decay, where a neutron in an atomic nucleus is transformed into a proton, an electron, and an antineutrino.
Is bombardment of alpha particles on beryllium artificial radioactivity?
You can say that as long as the alpha particle itself is not originating from a radioactive element. If however one is able to isolate the helium nucleus from the elemental atom and then used for bombarding towards the beryllium then it is considered as an example of artificial radioactivity. Or the production of a radioactive element(synthetic element) like Francium can be considered artificial radioactivity.
Radioactivity is a tendency for an element or a material to?
Radioactivity is a property of certain elements or substances where they undergo spontaneous decay, emitting radiation in the form of particles or waves. This decay process can result in the release of energy and the transformation of the nucleus of the atom.
What part of the atom causes the nucleus to have a positive charge?
The protons in the nucleus are positively charged, and their presence is what gives the nucleus an overall positive charge. Electrons balance this positive charge with their negative charge, resulting in a neutral atom.
What causes radioactivity?
Radioactivity is caused by the instability of an atom's nucleus. An unstable nucleus can emit particles or energy in the form of radiation in order to become more stable. This process is known as radioactive decay.
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.
Where does radioactivity start in an atom?
Radioactivity starts in an atom's nucleus, specifically when the nucleus is unstable and tries to become more stable by emitting particles such as alpha or beta particles, or energy in the form of gamma rays. This process is known as radioactive decay.
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 causes the temperature to change the crust of earth to the core?
Pressure and radioactivity.
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
