I WONDER - How Are The Elements On The Periodic Table Grouped?

The video tutorial explains the concept of groups in the periodic table, highlighting that there are 18 groups, each with distinct properties. It provides examples of noble gases and alkali metals, describing their positions and characteristics. Noble gases, found in the last column, are stable due to a full outer electron shell, while alkali metals, in the first column, are highly reactive with one outer electron. The video also notes that the periodic table is color-coded to clearly show these groups.

How many groups are there in the periodic table?

• 18

• 12

• 24

• 30

Where are noble gases located in the periodic table?

• First column

• Middle section

• Last column

• Second column

What makes noble gases very stable?

• They have a full outer shell of electrons

• They have no electrons

• They have a half-filled outer shell

• They have two electrons in the outer shell

Which group of elements is known for having one electron in their outer shell?

• Noble gases

• Alkali metals

• Transition metals

• Halogens

How do alkali metals differ from noble gases?

• Alkali metals are found in the last column

• Alkali metals have a full outer shell

• Alkali metals are less reactive

• Alkali metals are very reactive
