Solution
The electron configuration of atoms can help determine their location on the Periodic Table and whether they are metals, nonmetals, or metalloids.
-
Gns2np5: This electron configuration corresponds to the elements in the p-block of the Periodic Table. The last electron resides in the p orbital. These elements are typically nonmetals.
-
Gns2: This electron configuration corresponds to the elements in the s-block of the Periodic Table. The last electron resides in the s orbital. These elements are typically metals.
-
Gns2md10np4: This electron configuration corresponds to the elements in the d-block and p-block of the Periodic Table. The last electron resides in the p orbital, but there are also electrons in the d orbital. These elements can be metals, nonmetals, or metalloids.
So, the completed table would look like this:
| Electron Configuration | Location of Elements | Metals or Nonmetals? |
|---|---|---|
| Gns2np5 | p-block | Nonmetals |
| Gns2 | s-block | Metals |
| Gns2md10np4 | d-block, p-block | Metals, Nonmetals, Metalloids |
