- For Example:
Radius of the sun = 696,000.0 kilometer
Radius of the sun can also be written as =
Size of bacterial cell = millimeter
Size of bacterial cell can also be written as =
Answer: The four hybridized orbitals on Sb makes up the sigma bonds between Sb and F in antimony(iii) fluoride ,
Explanation:
According to VESPR theory:
Number of electrons around the central atom :
V = number of valence electrons
N = number of neighboring atoms
C = charge on cation
A = charge on an anion
In antimony(III) fluoride ,
Antimony being central atom: V= 5,N =3,C=0,A=0
Number of electrons :
Number of electrons around the central atom are 4 which means that molecule has four
hybridized orbitals.
