Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen). The peri...

The number of protons in an atom equals the number of ___. The sum of an atom's protons and neutrons is its What nuclide has 27 protons and 33 neutrons? The atomic mass is equal to: A. the number of neutrons. B. the number of protons plus the number of electrons. C. the number...
Thus, a chlorine ion has 18 electrons. Finding the Number of Subatomic Particles in Isotopes Isotopes are forms of the same element with different numbers of neutrons. The number of protons cannot be changed since once that number (Z) changes, so does the element. When talking about isotopes...
Isotopes of a chemical element are atoms with the same numbers of protons, but different numbers of neutrons. The number of protons is determined from the element's atomic number in the periodic table. The numbers of neutrons differ by one or more. ...
