Indicate the number of protons and the number of neutrons in each of the following nuclides: (a) \displaystyle _{8}^{15} O (b) \ \displaystyle _{15}^{32} P (c) \ \displaystyle _{53}^{131} I The electron in a hydrogen atom with an energy of...
Find the number of electrons required to make up a charge of -32 micro C. An element that has the electron configuration (Ne)3s2 is in the group: a. 2. b. 5. Determine the number of (a) electrons, (b) protons, and (c) neutrons in iron (2656 Fe). ...
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 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 ...
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 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 number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope...
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 Chapter 2/ Lesson 1 430K What is atomic number, mass number and atomic mass? Learn what ...
