Chemistry covLent bonds
Which of the following substances has the lowest boiling point
CO
Which statement is true about a molecule of H2?
Each atom has an electron configuration like that of helium, The electrons from both atoms travel within the molecular orbital
Which compound most likely has the greatest bond energy?
HF; H—F bond length 92pm
If two covalently bonded atoms move closer than a distance of the bond length, the potential energy of the atoms
Increases
The bond between which pair of elements listed in the table below will most likely have the least ionic character
O and H
Non polar covalent bonds are not common because
One atom usually attracts electrons more strongly than the other
Bond energy is the energy is the energy
Required to break one mole of similar bonds in a compound
Bond length between two bonded atoms is
The separation at which their potential energy is minimum
A single covalent bond involves the sharing of
Two electrons
The electrons involved in the formation of a covalent bond are
Valence electrons
