Where is curium found?
Curium does not occur naturally; it is typically produced artificially in nuclear reactors through successive neutron captures by plutonium and americium isotopes.
How do you make curium?
Curium can be made in very small amounts by the neutron bombardment of plutonium in a nuclear reactor. Minute amounts may exist in natural deposits of uranium. Only a few grams are produced each year.
What is the atomic mass of potassium?
39.0983 u
Potassium/Atomic mass
How many neutrons are in potassium 43?
It is the number under the element symbol. For potassium it is about 39. This means that the atomic weight is 39 for both protons and neutrons. Since we know that the number of protons is 19 we can calculate the number of neutrons (39 19) as 20.
What is the mass number of potassium?
How many neutrons are in Cm?
What are the mass and neutron numbers of potassium?
Mass numbers of typical isotopes of Potassium are 39; 41. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.
What are the mass numbers of dysprosium isotopes?
Mass numbers of typical isotopes of Dysprosium are 156-164. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.
How are the number of electrons in a potassium atom affected?
The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Potassium is 19. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
Why is the element dysprosium used in nuclear reactors?
Dysprosium is used for its high thermal neutron absorption cross-section in making control rods in nuclear reactors, for its high magnetic susceptibility in data storage applications. Dysprosium is a chemical element with atomic number 66 which means there are 66 protons in its nucleus.
