In this model the electrons are
considered fruits
-
the smallest component of an
element
-
the state in which electrons
are most probably located
-
the state of an atom when an
electron move to higher energy level
-
a particle with no charged
-
this mass is equal to the sum
of proton and neutron
-
positive ions
-
a model of the atom which had a
central nucleus surrounded by electrons in orbits
-
negative ions

particles contained in the atom
-
atoms of the same element with
the same number of protons but a different number of neutrons
-
the latest atomic model
-
the outermost electrons in an
atom
-
in this experiment, a foil is
bombarded with alpha particles
-
a positively charged particle
-
a negatively charged particle
-
when neutral atoms lose or gain
electrons they become this
