Given the following electron configuration:
1s²2s²2p⁶3s²3p⁶4s²3d¹⁰
What is the element?
a. Copper b. Zinc c. Ferrum
Zinc
True or False: In Hund's rules, electrons with the same spin can occupy the same orbital
False because electrons with the same spin repel each other because of its negative charge.
If the element is in the p block, what orbital will the electron configuration end with?
p orbitals
What are the shapes of all of the orbitals in 2D?
circle and dumbell
What does the coefficient indicate in electron configuration?
The energy level
What is the maximum number of electron in the 3rd energy level of an atom?
8

precisely known
Using the Aufbau principle, what comes after 4f?
5d
What indicates two electrons in the same suborbital spinning in opposite directions?
2 half arrows
How does the electron configuration of an element relate to its position on the periodic table?
Coefficient: tells what period it's in
Orbital: tells the block
The electrons added up represents the atomic number of the element.
