AlP
Element X has 3 valence electrons. What charge would it form?
3+
Element X has 5 valence electrons. What charge would it form?
3-
Element x has 5 valence electrons
Element y has 1 valence electron
What would the formula of a compound formed between these 2 atoms?
Y3X (Metals have low valence electrons so it has to go 1st)
X-X (bond length = 200 pm)
Y-Y (bond length = 250 pm)
Z-Z (bond length = 300 pm)
Which of these has the lowest bond dissociation energy?
Z-Z
What is the relationship between bond length and bond dissociation energy?
Inverse
Long length = low bond energy
Short length = high bond energy
