Is P4 covalent or ionic?

Is P4 covalent or ionic?

a) P4: is a molecular non-polar (pure) covalent molecule. Only London dispersion forces can act between its molecules b) Na3PO4 is an ionic solid. It will form a crystal lattice. c) Os is a metal, so it will have metallic bonding between its atoms.

Is phosphorus and oxygen ionic or covalent?

Both oxygen and phosphorus are typical nonmetals. When two nonmetals (H, B, C, N, O, F, Si, P, S, Cl, Br, I) combine to form a binary compound, the bond is always covalent. The phosphorus-oxygen bonds are covalent both in phosphorus(III) oxide (P4O6) and phosphorus(V) oxide (P4O10).

Why is phosphorus oxygen bond strong?

The P=O. bond, with its bond energy of 575 kJ mol−1, is one of the strongest double bonds in chemistry, and the Wittig reaction is irreversible and is driven forward by the formation of this P=O. bond.

What type of bond is phosphorus and fluorine?

Phosphorus and fluorine together form phosphorus trifluoride, or PF3.

Can P and CL form a covalent bond?

The two fluorine atoms form a stable F 2 molecule by sharing two electrons; this linkage is called a covalent bond. The valence electrons of phosphorus and chlorine. Phosphorus must combine with three chlorines to complete its valence shell. (See Figure 5.)

Which is the most reactive species of phosphorus?

Phosphorus occurs in at least 10 allotropic forms, the most common (and reactive) of which is so-called white (or yellow) phosphorus which looks like a waxy solid or plastic. It is very reactive and will spontaneously inflame in the air so it is stored underwater.

How does vitamin D affect phosphorus?

Vitamin D functions by stimulating intestinal calcium and phosphorus absorption, by stimulating bone calcium mobilization, and by increasing renal reabsorption of calcium in the distal tubule. These functions on bone and possibly kidney, but not intestine, require the parathyroid hormone.
