2.1- Isotopes & Atomic Structure Flashcards
What is the definition of an isotope?
atoms of the same element that contain an identical number of protons, but a different number of neutrons
Where is a proton located in an atom?
in the nucleus
Where is a electron located in an atom?
outside the nucleus
Where is a neutron located in an atom?
in the nucleus
What is the charge of a proton?
+1
What is the charge of a electron?
-1
What is the charge of a neutron?
no charge
What is the function of a proton?
-provide the attractive electrostatic central force that binds the atomic electrons
-number of protons in the nucleus is the defining property of an element(referred to as the atomic number)
What is the function of a electron?
generates an electric field that exerts an attractive force on a particle with a positive charge, such as the proton, and a repulsive force on a particle with a negative charge
What is the function of a neutron?
to contribute to the binding energy (or nuclear glue) that holds the nucleus itself together.
Why are isotopes useful in scientific research?
Isotopes have unique properties, and these properties make them useful in diagnostics and treatment applications

Look up different elements and identify atomic mass, number of electrons, protons, neutrons, and identify the element.
