An atom has an atomic number of 12 and a mass number of 25. how many neutrons does the atom have? How can you find atomic number from mass number? Which of among the atomic number, mass number and isotopes distinguishes one element from one another? Explain your answer. ...
The reason increasing atomic number doesn't always equate toincreasing massis because many atoms don't have the same number of neutrons and protons. In other words, severalisotopesof an element may exist. Size Matters If a sizeable portion of an element of lower atomic number exists in the fo...

A chemical element may be composed of a single or multiple isotopes. Each isotope of an element has the same number of protons in its nucleus but different numbers of neutrons. For example, naturally occurring carbon is composed primarily of two isotopes: 12C, whose nuclei contain six protons ...
