Answer:
Answer: If the number of electrons in the outer shell is between one to four, the compound is said to have positive valency. For compounds with electrons four, five, six, or seven, the valency is determined by subtracting the electron from eight. Oxygen is a colorless and odorless gas that people need to breath.
