Answer» Answer: GROUPS are numbered from 1 to 18. From left to right in the periodic table, there are two groups (1 and 2) of elements in the s-BLOCK, or hydrogen block, of the periodic table; ten groups (3 through 12) in the d-block, or transition block; and six groups (13 through 18) in the p-block, or main block. |
