To determine which of the given elements are isotopes, we need to follow these steps:1. Understand the Definition of Isotopes: - Isotopes are atoms of the same element that have the same atomic number but different mass num

Although their importance in iron production in some supernovae and in the production of rare isotopes of carbon, nitrogen, and oxygen in novae has been known for some time, binary stars have been treated only in isolation. Some effort to redress this situation was made in 1998 when Tout ...
Isotopes:There are some molecules that contain the same atomic number, but they contain different atomic mass such types of molecules are called isotopes. For example, hydrogen have three isotopes , 11H,12H,13H.Answer and Explanation: The isotopes are similar in atomic number and different in ...

An element is a substance completely made up of one atom. Thus, the periodic table of elements is effectively a list of all known types of atoms. However, the atom itself is not the smallest known particle, but instead each atom is made up of three indiv
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
Radioactive Elements & Decay | Overview & Examples from Chapter 3 / Lesson 12 101K Learn what radioactive elements are and identify radioactive materials or isotopes. Understand the mechanisms behind different types of radioactive decay. Related...
The elements that are formed naturally bynuclear fissionor through the intentional synthesis in nuclear reactors or particle accelerators are calledRadio Active Elements. All elements can have radioactive isotopes. If enough neutrons are added to an atom, it becomes unstable and decays. The increasing...
To be an element, a substance has to at least have protons, since these particles define the type of element. Elements consist of atoms, which contain a nucleus of protons and neutrons surrounded by a cloud or shell of electrons. Elements are considered the basic building blocks of matter be...
