New cards
bond energy ___ with bond order
increases
2
New cards
define bond energy (BE)
energy needed to overcome attraction between nuclei and the shared electrons. strong the bond, higher bond energy.
3
New cards
define bond length
distance between nuclei and bonded atoms
4
New cards
bond order and bond length are directly/inversely proportional
inversely
5
New cards
shorter the bond lengther ___ bond energy
higher
6
New cards
trend for bond length
increases down group, decreases across a period
7
New cards
trend for bond energy (inverse of bond length)
decrease down group, increase across period
8
New cards
equations when solving for deltaH using bond energy
