PPT-4.8 Trends in Periodic Properties

The atomic size of representative elements is affected by the attractive forces between the protons in the nucleus and the electrons in the outermost energy level Learning Goal Use the electron configurations of elements to explain the trends in periodic properties . Chapter 4 and 11 (the parts we didn’t get to last test). What is the periodic table?. periodic- a regular repeating pattern. periodic table- arrangement of elements so that their physical and chemical properties follow a regular repeating pattern. What makes up matter?. By Amelia. Atoms. : an atom is the smallest particle of an element. Atomic number. : the number of protons in a nucleus is the elements atomic number. Each element is made of one kind of atom, so elements are called pure substances . . 9/8/15. Elements come in different sizes. Which do you think is the biggest and why?. Objective .
