The diagram which shows electrons violating the Pauli exclusion principle is: C. a box containing an up and a down arrow and 2 other up arrows.
The Pauli exclusion principle can be defined as a principle which states that no two electrons (fermions) in a single atom can have the same values for all four (4) of their electronic quantum numbers.
Furthermore, this principle states that the orbital of an atom can only contain a maximum of two electrons, and they must have opposing spin orientations.
In conclusion, the diagram which shows electrons violating the Pauli exclusion principle is a box containing an up and a down arrow and 2 other boxes with 2 up arrows,that are having the same spin orientations as shown.

(2) gains three electrons and becomes a negatively charged ion
(3) loses one electron and becomes a positively charged ion
(4) loses three electrons and becomes a positively charged ion
Answer: (3) loses one electron and becomes a positively charged ion
Explanation:
Lithium bromide is formed by combination of lithium cation and bromine anion.
Electronic configuration of lithium:
Lithium atom will loose one electron to gain noble gas configuration and form lithium cation with +1 charge.
Electronic configuration of bromine:
Bromine atom will gain one electron to gain noble gas configuration and form bromide ion with -1 charge.
In lithium bromide, one electron from lithium metal gets transferred to bromine atom.

Valence electrons are the electrons that reside in an atom's outermost shell. The role of valence electrons in determining an atom's reaction makes them crucial. You can count how many electrons are at the highest energy level by writing an electron configuration.
How do the valence electrons function?
The electrons in an atom's outermost shell are called valence electrons. … Because the electrons in the outermost shells of two atoms are the first to come into contact with one another and are the ones that control how an atom will react in a chemical reaction, when two atoms interact.
The outer-shell electrons of an atom are known as valence electrons. The valence electrons in an atom control its reactivity.
