Problems and Solutions of
bond
Problem
:
Why is a filled valence
shell often called an octet?
With
the exception of He, which has 2 valence electrons, the closed shell/noble gas
configuration has eight electrons in its valence shell.
Problem
:
Which atom has a partial
negative charge in a B-H bond?
Because
H is more electronegative than B, H has a partial negative charge.
Problem
:
Which bond should be longer,
F-F or Cl-Cl?
Because
Cl is in period 3 and F is in period 2, the Cl atom is larger than the F atom.
This means that the Cl-Cl bond should be larger.
Problem
:
Which bond should be
stronger, H-F or H-Cl?
Because
F is both smaller and more electronegative than Cl, it should have a shorter
and stronger bond with H than has Cl.
