What is the atomic number of aluminium? What is the atomic number of mercury? What is the atomic number of hydrogen-2? What is the atomic number of phosphorus? What is the number of neutrons in sulfur? What is the atomic number for uranium?
Atomic number Z represents the number of protons per atom. Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass ...
The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. A radioactive isotope is one that breaks apart and gives off some form of radiation. About the only isotope of any use is polonium-210. ...
The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element ...
Does alpha radiation change the mass number of an atom? Does polonium-210 undergo alpha or beta decay? Is energy absorbed during beta decay? How does alpha decay release protons and neutrons? Does alpha decay release electrons? Does beta decay result in an ion?
uranium 238- the commonest isotope of uranium; it is not fissionable but when irradiated with neutrons it produces fissionable plutonium 239 pitchblende,uraninite- a mineral consisting of uranium oxide and trace amounts of radium and thorium and polonium and lead and helium; uraninite in massiv...
Question: What happens to the atomic number in positron decay? Positron Decay: Positron decay is more commonly known as beta plus decay. It is the form of beta decay characterized by ejecting a positron from the nucleus rather than an electron. The opposite charge of the ejected particle also...

The number of protons in the nucleus is called the atomic number. The atomic number of each element is unique. The combined number of protons and neutrons in an atom is called the atomic mass number. While theatomic numberalways stays the same. Some elements have atoms with different atomic...
