Structural and Electronic Formulas of SO3

The chemical formula of sulfur trioxide is SO3. It is a colorless, pungent gas that is highly reactive and can be dangerous when inhaled. Here are the structural and electronic formulas of SO3:

Structural Formula: The structural formula of SO3 shows the arrangement of atoms in a molecule. In the case of SO3, it consists of one sulfur atom (S) bonded to three oxygen atoms (O) through double bonds. The sulfur atom is in the center, and the oxygen atoms are arranged around it. The structural formula of SO3 can be represented as:

      O
       ||
O = S = O
       ||
      O

Electronic Formula: The electronic formula of SO3 represents the distribution of electrons in the molecule. In the case of SO3, each oxygen atom contributes six valence electrons, and the sulfur atom contributes six valence electrons. The total number of valence electrons in SO3 is 24. The electronic formula of SO3 can be represented as:

O: ••
S: ••
O: ••

Structural and Electronic Formulas of PH3

The chemical formula of phosphine is PH3. It is a colorless, flammable gas with a pungent odor. Phosphine is commonly used in organic synthesis and as a reducing agent. Here are the structural and electronic formulas of PH3:

Structural Formula: The structural formula of PH3 shows the arrangement of atoms in a molecule. In the case of PH3, it consists of one phosphorus atom (P) bonded to three hydrogen atoms (H). The phosphorus atom is in the center, and the hydrogen atoms are arranged around it. The structural formula of PH3 can be represented as:

     H
      |
H - P - H
      |
     H

Electronic Formula: The electronic formula of PH3 represents the distribution of electrons in the molecule. In the case of PH3, the phosphorus atom contributes five valence electrons, and each hydrogen atom contributes one valence electron. The total number of valence electrons in PH3 is eight. The electronic formula of PH3 can be represented as:

H: •
P: •••
H: •
