LT#3: Periodic Table Flashcards
1
Q
How is the periodic table influenced by the Aufbau Principle?
A
Elements are arranged by the filling order of quantum orbitals from lowest to highest energy
2
Q
The period number of an element correspond to…
A
The “n” value of the outer most electron on an element.
Exceptions: d-orbitals lag 1 n level behind, f-orbitals lag 2 n levels behind due to filling order.
3
Q
The number of elements in a period is dictated by….
A
The number of electrons the orbitals of that energy level can hold.
4
Q
Describe the groups located in each orbital block
A
s-block (1 and 2)
p-block (13-18)
d-block (transition metals, 3-12)
f-block (2 rows at bottom)
5
Q
The group number of an element indicates…
A
the amount of valence electrons.
