Question

(6) Predict the number of valence electrons for each of the following elements (4 pts)

(a) P
(b) Ar
(c) c
(d) Ni

Answer 1

P = 5, Ar = 8, C = 4, Ni = 2

Step-by-step explanation:

All these answers can be based off which column of the periodic table each element is in. This does exclude the transition medals in between the 2nd and 13th columns. Column 1 = 1, Column 2 = 2, Column 3 = 3 and so on. Transition metals can be determined based on their electron configuration, which in this case, Ni has 2 electrons in its outer most shell.
