Part a. From the periodic table, identify the atomic number (Z) of carbon (C), oxygen (O) and tin (Sn).
Go to the periodic table; identify carbon, oxygen and tin; and determine the atomic number of each element.
Carbon has an atomic number of 6, oxygen has an atomic number of 8 and tin has an atomic number of 50.
Part b. From the periodic table, identify the elements with the atomic numbers of 3, 12 and 29, respectively.
Go to the periodic table and find the elements that have the atomic numbers of 3, 12 and 29.
Lithium (Li) has an atomic number of 3, magnesium (Mg) has an atomic number of 12 and copper (Cu) has an atomic number of 29.
How might the number of protons and electrons in an atom affect the properties of that atom? How does the number of protons contained in an atom relate to the structure of the periodic table?
