*variants of an ‘element’*
(in terms of amount of ‘neutrons’)
.
*”isotopes” are variants of a particular ‘chemical element’ which differ in ‘neutron #’*
.
(all ‘isotopes’ of a given ‘element’ have the same # of ‘protons’ in each ‘atom’)
(the term ‘isotope’ is formed from the greek roots ‘isos’ (ἴσος “equal”) and ‘topos’ (τόπος “place”), meaning “the same place”;
(thus, the meaning behind the name is that different ‘isotopes’ of a single ‘element’ occupy the same ‘position’ on the ‘periodic table’)
(the # of ‘protons’ within the atom’s ‘nucleus’ is called ‘atomic #’ and is equal to the ‘# of ‘electrons’ in the ‘neutral’ (aka ‘non-ionized’) atom)
(each ‘atomic #’ identifies a specific ‘element’, but not the ‘isotope’)
(an ‘atom’ of a given ‘element’ may have a ‘wide range’ in its # of ‘neutrons’)
(the # of ‘nucleons’ (both ‘protons’ + ‘neutrons’) in the ‘nucleus’ is the atom’s ‘mass #’, and each ‘isotope’ of a given ‘element’ has a different ‘mass #’)
.
(for example, ‘carbon-12’ / ‘carbon-13’ / ‘carbon-14’ are 3 ‘isotopes’ of the element ‘carbon’ with (mass #: ’12’ / ’13’ / ’14’) respectively)
.
(the ‘atomic #’ of ‘carbon’ is ‘6’, which means that every ‘carbon atom’ has 6 ‘protons’, so that the ‘neutron #’ of these ‘isotopes’ are (‘6’ / ‘7’ / ‘8’) respectively)
.
*’caesium’ has 55 protons*
*so ‘caesium-133′ has ’55 protons’ / ’78 neutrons’*
