Electron Configuration and Antimony Concepts

This video tutorial explains how to write the electron configuration for antimony (Sb), a neutral element with 51 electrons. It covers two methods: using the periodic table's orbital blocks and the diagonal rule. The video also demonstrates how to write the condensed electron configuration using the noble gas Krypton (Kr) as a reference. The tutorial concludes with a note on variations in writing electron configurations, such as the order of 5s2 and 4d10.

What is the atomic number of antimony (SB)?

• 52

• 51

• 50

• 49

Why is antimony considered a neutral element?

• It has more protons than electrons.

• It has more electrons than protons.

• It has an equal number of protons and electrons.

• It has no protons.

Which noble gas is used in the condensed electron configuration of antimony?

• Argon

• Neon

• Krypton

• Xenon

What is the purpose of using a condensed electron configuration?

• To simplify the representation.

• To add more electrons.

• To remove electrons.

• To make the configuration longer.

In the periodic table method, what is the ending electron configuration for antimony?

• 5s2 4d10 5p2

• 5s2 4d10 5p3

• 5s2 4d8 5p3

• 5s2 4d10 5p6

How many electrons can the 'p' orbital hold?

• 8

• 4

• 6

• 2

What is the diagonal rule used for?

• To determine electron configuration.

• To find the atomic mass.

• To determine the number of protons.

• To calculate the number of neutrons.

Which electron configuration notation might sometimes be written differently?

• 4d10 before 5p3

• 5p3 before 5s2

• 5s2 before 4d10

• 4d10 before 5s2

What is the significance of the 5p3 configuration in antimony?

• It is irrelevant to the configuration.

• It shows the end of the electron configuration.

• It represents the start of the configuration.

• It indicates a full 'p' orbital.
