Another name for the two sub-atomic particles found in the nucleus is ____________. 4. What are the sub-atomic particles found outside of the nucleus? 5. Which particle has a positive charge? 6. Which particle has a neutral charge? 7. Which particle has a negative charge? 8. An element’s atomic number represents the number of ____? 9. The atomic mass represents the sum of what two particles? 10.Elements shown on the periodic table have a ______ charge. 11.An element that has either a positive or negative charge is ___? 12.What is a positively charged element called? 13.An anion is a ____. 14.If an element has a negative charge, it has more ____ than ____. 15.Atoms of the same element that have different numbers of neutrons are called ___. 16.What do you change if you change the number of protons of an atom? 17.What do you change if you change the number of electrons of an atom? 18.Adding another neutron to an atom gives a new isotope with a new _______ ______. 19.The periodic table of elements shows all the elements in order of their ________ ______. 20.The columns of the periodic table are called _____________ or ___________. 21.The rows of the periodic table are referred to as ___________. 22.The first group of the periodic table is the _____ _____. 23.What is the second group of the periodic table called? 24.What is the middle and largest group of elements of the periodic table called? 25.Which group of elements of the periodic table, found to the far right, is the least reactive? 26.What is the second from the right group of elements of the periodic table? 27.What do you call the elements along the “stair step” on the right side of the periodic table? 28.What type of elements are those found to the top right in the periodic table? 29.What type of elements are those found to the left of the stair step (not including metalloids) in the periodic table? 30.Why aren’t the atomic masses in the periodic table whole integers?
