Photoelectric Effect
Does this show that light has wavelike or particle like properties? Why? What wouldthe results look like if they had only wave-like properties?

Write the electron configurations for C, N,
and O. Place in order of increasing ionization
energy, increasing electron affinity and
increasing electronegativity. For each
characteristic, do these follow the trend?
Why or why not?
Wrong Answer 1:All: C, N, O
Yes
Because the trend goes up and tothe right.
