Phosphorus has an electronic configuration in the simple form 2,8,5 and a spdf configuration of 1s² 2s² 2p⁶ 3s² 3p³.
The valence electrons in phosphorus (the electrons available for bonding) are 5. As a result, an atom of phosphorus shares its electrons with another atom to form COVALENT bonds. This is ideal since it would take a high amount of energy to release these five electrons, and it would be unlikely for atoms to lose 5 electrons to donate to phosphorus.

Explanation:
Answer:
The correct answer would be D.Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.
Alveoli are tiny sacs which form the site of gas exchange in the lungs.
The features of alveoli which help in gas exchange are:
- They increase the surface area in the lungs thus, more space is available for gas exchange.
- They have very thin walls, as thin as the thickness of a single cell only.
- They are surrounded by a bunch of thin capillaries which exchange gases with alveoli.
The tissue that is like the skin is DERMAL tissue
The fleshy part of a plant is the GROUND tissue
the tissue that is like the cardiovascular system is the VASCULAR tissue
As animals move up in the food chain they start to have larger competition for food with other animals, deer compete with elk and even rodents that eat the same food as them. They must fight for food and survival.
