However, radon is radioactive, hence its name, and its nucleus tends to break down into other elements, particularly lead.Answer and Explanation: The atomic number of radon is 86. The atomic number is equal to the number of protons in an element. Each element has a characteristic number of...
How many protons are in an isotope of sodium with a mass number of 25? What is the relationship between atomic mass and mass number? What is relative atomic mass? What is the atomic number of germanium? An atom has an atomic number of 12 and a mass number of 25. how many neutrons ...
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 mass number of lithium is 7. The mass number of any element is equal to its number of protons and neutrons. You can figure out the number of... Learn more about this topic: Atomic & Mass Number | Overview & Difference from
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. 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 atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s22p2, since its atomic ...
neutrons are found in the nucleus of the atom, while the electrons are outside the nucleus. The atomic number is the number of protons, while the mass number is the number of protons and neutrons. If an element is not charged, the number of electrons will equal the number of protons. ...
Radon-222 undergoes alpha decay to become What is the nuclear equation for beta decay of Au-198? Does beta decay always emit protons? What isotope does americium-241 turn into after alpha decay? What happens to the atomic number in positron decay?
Sources:Francium occurs as a result of an alpha disintegration of actinium. It can be produced by artificially bombarding thorium with protons. It occurs naturally in uranium minerals but there is probably less than an ounce of francium at any time in the total crust of the earth. ...
