Soil is made from dead plants, animals, and rocks.
<span>Xe = VIII = 8 valence electrons
F = VII = 4 (7 ve) = 28 valence electrons</span>
total ve = 8 + 28 = 36 ve
<span>36 - 4(2) = 28 ve
(there are 2 electrons in each bond x 4 bonds)</span>
<span>28 - 4(6) = 4
(We assign the remaining electrons to F atoms)</span>
<span>4 - 2(2) = 0
(Therefore 4 electrons left => we have 2 lone pairs)</span>
The steric number = No. of
σ bonds + #lone pairs
= 4 σ bonds + 2 lone pairs
= 6 => d²sp³ (6 hybrid orbitals)
<span>4 bonds + 2 lone pairs
=> square planar</span>
Answer and Explanation:
(a) MONATOMIC CATION: Monatomic cation are those cation in which only one atom is present
Example : ![Na ^+,Ca^2+](https://tex.z-dn.net/?f=Na%20%5E%2B%2CCa%5E2%2B)
(b) MONATOMIC ANION : Monatomic anion are those cation in which only one atom is present
Example : ![Cl^-,N^{3-}](https://tex.z-dn.net/?f=Cl%5E-%2CN%5E%7B3-%7D)
(C) Polyatomic Cation : Polyatomic cations are those cation which contains more than one atom
Example : ![NH_4^+,NO_3^-](https://tex.z-dn.net/?f=NH_4%5E%2B%2CNO_3%5E-)
(C) Polyatomic Anion : Polyatomic anions are those cation which contains more than one atom
Example : ![SO_3^{2-}PO_4^{2-}](https://tex.z-dn.net/?f=SO_3%5E%7B2-%7DPO_4%5E%7B2-%7D)
