I Review I Constants I Periodic Table Learning Goal: To understand the arrangement of the periodic table and identify certain groups of elements by name (e.g. halogens, metals, lanthanides etc.). Groups and periods The periodic table is a list of elements arranged by atomic number. As you can see in the image (Figure 1) below, the atomic number for each Columns in the periodic table are called groups, and the rows are called periods. Notice that the groups are labeled 1 to 18 and the periods are labeled 1 to 7. Groups 1, 2, and 13 to 18 are called the main group elements, groups 3 to 12 are the transition elements, and the bottom two rows are called the lanthanides and actinides, respectively. element is the whole number in the cell. The atomic This table gives properties and alternate names for some of the groups: mass, written below the symbol here although it may appear elsewhere in some periodic tables, is the average mass of the isotopes of that element. Group Name Properties 1 Alkali metals React to form 1+ ions. 2 Alkaline earths React to form 2+ ions. 17 Halogens React to form 1- ions. Rare gases 18 (noble gases) Stable and unreactive. (Elements from other groups form ions to achieve the same number of electrons as a noble gas.) Metals vs. nonmetals Notice the heavy zigzag line running diagonally across the right part of the table. This line separates metals (below and to the left of the line) from the nonmetals (above and to the right of the line). Metals tend to lose electrons to form positive ions, whereas nonmetals tend to gain electrons to form negative ions. Figure 1 of 1 atomic number 1.008 atomic mass
