Concept explainers
(a)
Interpretation:
The following atoms need to be ranked in increasing order of electronegativity:
Si, P, S
Concept Introduction:
Electronegativity is the tendency of an atom to pull bonding electrons towards it when two atoms formed a bond. Higher the electronegativity value, the higher the tendency to pull electrons towards the atom.
(b)
Interpretation:
The following atoms need to be ranked in increasing order of electronegativity:
Be, Mg, Ca
Concept Introduction:
Electronegativity is the tendency of an atom to pull bonding electrons towards it when two atoms formed a bond. Higher the electronegativity value, the higher the tendency to pull electrons towards the atom.
(c)
Interpretation:
The following atoms need to be ranked in increasing order of electronegativity:
Se, Cl, Br
Concept Introduction:
Electronegativity is the tendency of an atom to pull bonding electrons towards it when two atoms formed a bond. Higher the electronegativity value, the higher the tendency to pull electrons towards the atom.
