SOMETIMES
Be able to write the electron configuration for some elements.
Example:
C = 1s(2) 2s(2) 2p(2)
Br = 1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 4s(2) 3d(10) 4p(5)
Be able to tell the VALANCE ELECTRONS and UNSHARED PAIRS for an element.
Example:
C = 1s(2) 2s(2) 2p(2) VE = 4 / USP = 2
Br = 1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 4s(2) 3d(10) 4p(5)
VE = 7 / USP = 1
Be able to draw and label ALL the parts of the wave
See Mrs. Krumpelman for help
Using the atom level - why is metallic salt used in fireworks?
As the salts absorb energy - they move to a high energy level - as they lose energy they give off light - different metallic salts give off different colors
