Name That Element
What element has the following electron configuration:
1s2 2s2 2p4
What is Oxygen
What is the electron configuration of Lithium?
1s2 2s1
What do arrows in an orbital diagram represent?
What are electrons?
How many electrons can go into each individual orbital?
Two
What element is found in period 3, group 2?
Magnesium
What element has the following electron configuration:
[Ar] 4s2 3d9
What is Copper
What is the electron configuration of Carbon?
1s2 2s2 2p2
The s block has how many lines and arrows when filled?
1 line, 2 arrows
Which sublevel fills first and why; 3d or 4s
What is 4s because even though it is in a higher principle energy level, it's shape makes it closer to the nucleus and therefore requires less energy to fill
What element is found in period 5, group 14?
Tin
What element has the following electron configuration:
[Xe] 6s2 5d1 4f14 5d9 6p2
What is Lead
What is the noble gas electron configuration of Arsenic?
[Ar] 4s2 3d10 4p3
The p block has how many lines and arrows when filled?
3 lines, 6 arrows
What is the Aufbau Principle?
Electrons fill lower-energy atomic orbitals before filling higher-energy ones
Why do we care about electron configurations?
Because they tell us about how atoms will interact with each other in a chemical reaction
What element ends on the following electron configuration:
4s1
What is Potassium
What is the noble gas electron configuration of Titanium?
[Ar] 4s2 3d2
The d block has how many lines and arrows when filled?
5 lines, 10 arrows
What principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers
What is the Pauli Exclusion Principle
What is the name of the last column on the periodic table?
Noble Gasses
What element ends on the following electron configuration:
5f7
What is Americium
What is the noble gas electron configuration of Osmium (Os)?
[Xe] 6s24f145d6
The f block has how many lines and arrows when filled?
7 lines, 14 arrows
What is Hund's Rule?
Every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
Why do atoms interact with each other?
In order to fill their valence electrons
