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 ...
Two or more atoms having the same atomic number but the different mass numbers can be known as isotopes. The atomic number denotes the number of protons inside the nucleus of an atom. The number of protons remains the same for all isotopes....
Their elemental affiliation is determined by the number of protons in the nucleus, which cannot change without changing the element. However, isotopes vary in the number of neutrons in their nuclei.Answer and Explanation: The formula for mass number is simple: Mass number = protons + neutrons ...
For example, the molecule having low symmetry has a C-1 point group (identity toll is only applied for such molecules). Answer and Explanation:1 Given data The given point group is {eq}\rm {T_d}{/eq}. The symmetry of the chemical compound is determined by the point group...
