Final answer:
To find an element on the periodic table with the group and period numbers, one should look at the intersection of the corresponding period (horizontal row) and group (vertical column). Each period is numbered 1-7, and groups are numbered 1-18. For instance, Boron (B) can be located in period 2, group 13.
Step-by-step explanation:
To find an element on the periodic table using the group and period numbers, you must understand how the table is arranged. Each horizontal row on the periodic table is known as a period, and each vertical column is referred to as a group. The periods are numbered from 1 to 7 starting at the top of the table and moving down, while the groups are numbered from 1 to 18 from left to right. With this knowledge, if you're given a period and group number, you locate the intersection of the corresponding period row and group column to identify the specific element.
For example, the element Boron (B) is found in period 2 and group 13. If you're given these numbers, you would look on the second horizontal row and the thirteenth vertical column to find Boron. Similarly, elements in the same group share similar chemical properties due to having the same number of valence electrons, as seen in families such as the alkali metals (Group 1) and noble gases (Group 18).
To better understand how the periodic table is organized, and to find other elements, you can look at a periodic table chart where the elements are already arranged by increasing atomic number and aligned into periods and groups accordingly.
