Understanding the Linus Pauling Diagram

This video tutorial by Diego Gomes from Descomplica provides an overview of the Linus Pauling diagram, a tool used to distribute electrons in an atom's electron shell in increasing order of energy. The tutorial explains the concept of energy levels and sublevels, detailing how electrons are distributed across these levels. It also demonstrates the construction of the Linus Pauling diagram and provides an example using the electron configuration of sodium. The video concludes with a call to action for viewers to engage with the channel and access additional resources.

What is the primary purpose of the Linus Pauling Diagram?

• To determine the atomic mass of an element

• To distribute electrons in an atom in order of increasing energy

• To calculate the number of protons in an atom

• To identify the type of chemical bonds in a molecule

How many levels or layers can electrons be distributed into according to the Linus Pauling Diagram?

• Five

• Six

• Seven

• Eight

Which sublevel can hold a maximum of 10 electrons?

• f

• s

• d

• p

How many electrons can the L level hold in total?

• 2

• 8

• 18

• 32

Which level can hold a maximum of 32 electrons?

• N

• M

• L

• K

What is the first step in constructing the Linus Pauling Diagram?

• Placing the sublevels in order of increasing energy

• Identifying the number of protons

• Drawing the atomic nucleus

• Calculating the atomic mass

In the Linus Pauling Diagram, which sublevel is filled first?

• d

• f

• s

• p

For the sodium atom with atomic number 11, what is the correct electron configuration?

• 1s2 2s2 2p6 3s1

• 1s2 2s2 2p6 3s2

• 1s2 2s2 2p6 3p1

• 1s2 2s2 2p6 3d1

Why do we place 3s1 instead of 3s2 for the sodium atom?

• Because 3s2 is not allowed

• Because 3s1 is more stable

• Because 3s1 has lower energy

• Because 3s2 would exceed the total number of electrons
