2.1 Flashcards
position, mass, charge, and function of a proton
nucleus, 1, +1, determines the charge and element
position, mass, charge, and function of an electron
outer rings, nothing, -1, reacts in a reaction and determines charge
position, mass, charge, and function of a neutron
nucleus, 1, +0, stabilize the nucleus,
isotope
a form of a chemical element in which the atoms have the same number of protons but with a different number of neutrons
atomic mass
protons and neutrons
element
part of something abstract
ion charge with protons
(+)
ion charge with neutrons
0
ion charge with electrons
(-)
why isotopes can be useful in scientific research
can be used as tracers
Determine the # of protons, electrons, and neutrons when given the element
protons+electrons equal the element mass
Determine the # of protons, electrons, and neutrons when given the atomic mass
mass is protons + neutrons, cant find electrons
Determine the # of protons, electrons, and neutrons when given the ion charge
protons (- or +) electrons, neutrons are unidentifiable
