Neutrons, Isotopes and Atomic Mass Number(p. 35)

Target: I know how to find the isotope, and the atomic mass number of an element, and how to name isotopes.

___

_____?

________?

________?

  • Elements always have the same number of protons, but can have different numbers of neutrons
  • The number of neutrons givesyou the isotope of the element
  • Isotopes can be radioactive or stable
  • Isotopes are named by the element name and their mass number
  • Theatomic mass number is the number of protons PLUS the number of neutrons
34 name that isotope
(34) Name that Isotope!

(Name each isotope below, and list the number of protons, neutrons, electrons)

summary p 35
Summary( p. 35):
  • (Write a 3 sentence summary, using the words “atomic number”, “neutrons”, “isotope” and “atomic mass number”)
