To find the number of neutrons in an atom, you need to find the mass number for each element. Theperiodic tablelists theatomic weightfor each element, which can be used to find mass number, For hydrogen, for example, the atomic weight is 1.008. Each atom has an integer number of neutro...
The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass number, A. The number of neutrons in an atom, the neutron number, is given by the quantity A-Z....
Describe the structure of an atom.An atom consists of a nucleus, which contains protons and neutrons, surrounded by electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons determines

What determines the atomic number of an atom? A. Number of electrons in the other shell. B. Mass of the atom. C. The number of neutrons. D. The number of protons. E. The number of protons plus neutrons. How many neutrons does eleme...
The total number of protons and neutrons in the nucleus of an atom. For example, nitrogen has 7 protons and 7 neutrons in its nucleus, giving it a mass number of 14. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton Mifflin Harcourt Publishin...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
If the atomic number of an element is 12 and the atomic mass is 25: a. How many protons are there in the nucleus? b. How many neutrons are there in the nucleus? c. How many electrons are in the atom? The number of in t...
