I am Lyosha [343]
The answer is 3). This is because elements are the simplest form of a substance, and cannot be broken down any further. Compounds on the other hand are much more complex than elements and can be broken down INTO elements. For example, Na, sodium, is an element and cannot be broken down further. H2O, water, is a compound and can be broken down into Hydrogen and Oxygen.

The sp3 hybridization has what percent s character and what percent p character respectively?
Salsk061 [2.6K]

Answer:

The sp³ orbital hybridization has 25% s-character and 75% p-character.

Explanation:

Hybridization refers to the process of mixing of a given number atomic orbitals to form equal number of new hybrid orbitals. The three types of hybrid orbitals are sp³, sp² and sp.

The<u> four sp³ hybridized orbitals</u> are formed by the mixing of <u>one s orbital and three p orbitals.</u>

Thus s-character in a sp³ hybridized orbital = (1÷4)×100 = 25%

and p-character in a sp³ hybridized orbital = (3÷4)×100 = 75%

<u>Therefore, the sp³ orbital hybridization has 25% s-character and 75% p-character.</u>
