What is the structure of p4?
After determining how many valence electrons there are in P4, place them around the central atom to complete the octets. The Lewis structure for P4 is more challenging than other Lewis structures because we the Phosphorous atoms are bonded in the shape of a pyramid with a triangular base.

- White phosphorus is made up of discrete P4 tetrahedra which are subjected to very high angular strain as the angles is 60 degrees. Red phosphorus is a polymer of P4 tetrahedra, which has much less angular strain. This high angular strain makes white phosphorus unstable and highly reactive.
- Methane (CH4) is made up of one carbon (C) and four hydrogen (H) atoms. There are four bonds and they are all covalent. Those examples have very simple chemical bonds. However, most compounds have combinations of ionic and covalent bonds.
- Compounds that contain both metals and nonmetals are usually ionic. For example, Na2SO4 contains a metal (Na) and nonmetals (sulfur and oxygen), and so is expected to be ionic. NH4Cl is an ionic compound. You might expect it to be molecular because it contains only nonmetals.
Phosphorus is a chemical element with symbol P and atomic number 15. Phosphorus is essential for life. Phosphates (compounds containing the phosphate ion, PO43−) are a component of DNA, RNA, ATP, and phospholipids.
- Serum phosphorus is measured in milligrams of phosphorus per deciliter of blood (mg/dL). According to Mayo Medical Laboratories, a normal range for adults is generally 2.5 to 4.5 mg/dL. The normal range varies slightly depending on your age.
- Phosphorus is a mineral that helps build strong bones and teeth. It assists in the conversion of food into energy and plays a role in metabolism. Phosphorus is found in foods such as high-protein meats and dairy, colas, whole grains and chocolate.

4P means 4 separate atoms of phosphorus ///// P4 means 4 atoms in a molecule of phosphorus. 4 Driving Forces of a chemical reaction.
- Chlorine is called Cl2 because it is a diatomic molecule. Diatomic means there are two atoms of the same elements in the molecule. There are other diatomic molecule, such as hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2). The chemical symbol of chlorine is only Cl.
- Other elements form diatomic molecules when evaporated, but these diatomic species repolymerize when cooled. Heating ("cracking") elemental phosphorus gives diphosphorus, P2. Sulfur vapor is mostly disulfur (S2). The bond in a homonuclear diatomic molecule is non-polar.
- Silicon has a giant covalent structure with strong covalent bonds between the atoms. This causes it to have the highest melting point compared to the other elements within the period. Phosphorus, Sulfur and Chlorine are all simple molecular substances which merely have Van Der Waals attractions between the molecules.
