Grouping the elements:
To determine the group to which the elements belong, we need to identify a certain characteristic or property that is shared among four of the elements.
Germanium: Germanium is a metalloid with atomic number 32. It is commonly used in semiconductors.
Gallium: Gallium is a soft silvery metal with atomic number 31. It is used in various electronic applications.
Potassium: Potassium is an alkali metal with atomic number 19. It is highly reactive and is commonly found in salts.
Silicon: Silicon is a metalloid with atomic number 14. It is a crucial element in the production of computer chips and solar cells.
Zirconium: Zirconium is a strong, corrosion-resistant metal with atomic number 40. It is often used in alloys and nuclear reactors.
Identifying the outlier:
By comparing the properties of the elements, we can see that all of them except for Potassium belong to the same group. The outlier in this case is Potassium.
Explanation:
The grouping of the elements is based on their chemical properties and characteristics. Germanium, Gallium, Silicon, and Zirconium all have similar properties as metalloids or metals, while Potassium is an alkali metal with different properties. The other four elements are commonly used in electronic applications and have similar chemical behaviors, whereas Potassium is highly reactive and is typically found in salts.
Conclusion:
Potassium is the element that does not belong to the group formed by Germanium, Gallium, Silicon, and Zirconium. It is important to analyze the properties of the elements to identify the outlier and determine the grouping.
