Is this electron configuration correct or incorrect?
Incorrect
Correct
Which one of these rules is not part of electron configuration
Electrons fill the lowest energy orbitals first
Within a sub level, always place one electron per orbital before pairing them
Each orbital can hold THREE electrons with opposite spins
Each orbital can hold TWO electrons with opposite spins
Looking at your periodic table, to which element does the following electron configuration belong to
Germanium
Selenium
Arsenic
Zinc
Looking at the electron configuration shown below, why is it incorrect?
The two arrows are not in the same orbital, they should have been paired before moving to another box.
The second arrow(electron) is not facing the same way the first arrow(electron) faces.
The middle row of 2p should have been left empty
The second arrow should have been facing up in the third box
