The chemical formula for phosphorus hydrogen is PH3.
linear formula
The formula PH3 represents one phosphorus atom and three hydrogen atoms. Therefore, PH3 has a total of four atoms.
Formula: PH3
Lewis dot structure
The electron dot structure for PH3, or phosphine, is H: :P: :H: :H. It shows phosphorus in the center with three pairs of dots representing the three hydrogen atoms bound to it. Each hydrogen atom shares one electron with phosphorus to form a covalent bond.
PH3 is an acid.It is a flammable substance.
Phosphorous Hydride = PH3
The formula of cyclopentane is C5H10. The electron dot structure of cyclopentane would show each carbon atom with four valence electrons forming single bonds with adjacent carbon atoms, resulting in a pentagon shape.
The electron-dot formula for HCl shows that hydrogen has 1 valence electron denoted as ● and chlorine has 7 valence electrons denoted as ●●●●●●●. The bond between hydrogen and chlorine is represented by a single line, indicating a single covalent bond.
Phosphine, or PH3, has (quite obviously) three hydrogen atoms singly bonded to a phosphorus atom. Because of the presence of a lone pair of electrons, the phosphorus atom is sp3 hybridized, and the electron orbitals adopt a tetrahedral configuration. As mentioned earlier, one orbital is non-bonding and thus the molecular shape is trigonal pyramidal.
The electron dot formula for SF6 would show 6 pairs of dots around the central Sulfur atom, representing the 6 Fluorine atoms bonded to it. The Sulfur atom will have 12 valence electrons around it in total.
