Copy of Electron Config and Ground State Diagrams (5/28/2026)

Write the electron configuration for each of the following atoms:

a.) K

b.) P

c.) Cu

d.) Ba

e.) Fr

f.) Kr

g.) Al

h.) C

i.) Eu

j.) Au

Determine which electron configurations are incorrect, then correct these that are incorrect.

If any of these are correct, for the blank that reads, "If incorrect, what should it be?" type - "No Change Needed"

a.) 1s2 2s2 2p6 3s2 3p6 4s2 4d10 4p5

Is it correct?

If incorrect, what should it be?

b.) 1s2 2s2 2p6 3s3 3d5

Is it correct?

If incorrect, what should it be?

c.) 1s1

Is it correct?

If incorrect, what should it be?

Determine which elements are represented by each electron configuration.

a.) oxygen (O)

b.) potassium (K)

c.) cobalt (Co)

d.) phosphorus (P)

e.) indium (In)

f.) rutherfordium (Rf)
