Question 1
Write the subshell electron configuration (i.e.1s2 2s2, etc.) for the Ni28 atom.
Your Answer:
Ni28 = 28 electrons = 1s2 2s2 2p6 3s2 3p6 4s2 3d8
Write the subshell electron configuration (i.e.1s2 2s2, etc.) for the K19 atom.
Your Answer:
K19 = 19 electrons = 1s2 2s2 2p6 3s2 3p6 4s1 Question 3
Write the subshell electron configuration (i.e.1s2 2s2, etc.) for the S16 atom and identify which are valence (outer shell) electrons and determine how many valence electrons there are.
Your Answer: S16 = 16 electrons = 1s2 2s2 2p6 3s2 3p4 = 6 valence electrons Question 4
