Explanation:
The periodic table is divided into 4 blocks; s-block, p-block, d-block and the f-block.
Elements found in the s-block are metals; alkali metals and alkali earth metals. Elements found in the p-block include metals and non-metals while those found in the d-block are metals (transition metals). The F-block elements are the radioactive elements.
Oxygen (O) and selenium (Se) are non-metals found in group 16 of the periodic table which is found in the p-block of the periodic table. The p-block is located on the right side of the periodic table. Generally, non-metals are poor conductors of electricity.
