We’re being asked to complete the first row of the table.


Recall that the symbol for an element or ion is as follows:




Recall that:


  • Atomic Mass = A number of protons + number of neutrons
  • Atomic NumberZ = number of protons = number of electrons
  • Net charge
    • number of electrons lost if positive (+)
    • number of electrons gained if negative (-)


The number of protons for each element is given in the second row.


For the 2nd Column


  • Recall that the number of protons is equal to the atomic number, thus in the periodic table, it is element 34 which is Selenium (Se).
