A high school chemistry teacher asks four student groups to determine the number of protons neutrons and electrons respectively present in an ion of Titanium Ti 2 Which student group provides the best answer Group one claims that there are 22 protons because this number identifies the element Ti they also claim there are 26 neutrons because when the protons and neutrons are added the number equals the atomic mass on the periodic table which is 47 87amu and there are 20 electrons because the ion has a 2 charge which indicates the atom lost two electrons Group two claims the number of protons is 26 because the number of neutrons is always the same when subtracted from the mass which is 48 the number of neutrons would then equal 22 and the number of electrons is 24 because the 2 charge indicates the atom gained 2 electrons O Group three claims that there are 22 protons in an atom of Ti so that means there are 24 neutrons because there is a 2 charge which indicates the atom lost 2 neutrons and there are 22 electrons because every atom has the same amount of protons and electrons Group four claims there are 20 protons because the atom lost 2 charges the number of neutrons is 28 because when added the number of neutrons and protons should equal 48 and there are 20 electrons because the number of electrons and protons should be the same
