Flashcards in Periodic Table Info Deck (4)
What does the group number represent?
The number of valence electrons overall
E.g. Ti = group 4, 4e overall ([Ar] 3d2 4s2)
What does the period represent?
Period = the s orbital number
Period number-1 = the d orbital number
period number-2 = the f orbital number (if applicable)
E.g. Ti = period 4 so [noble gas in period above] 4s, 3d
Don’t forget to add if s, d or p block
Learn all orbitals of each noble gas so it’s less confusing
