Question

Write the Family Name for: ​i) Most reactive Metals​​ii) Least Reactive NONMetals

​a) Alkali Metals, Noble Gases​​b] Alkaline Earth Metals, Noble Gases​​
c} Alkali Metals, Halogens​​d} Alkaline Earth Metals, Halogens​​
e} Transition Metals, Halogens​

Answer 1

The most reactive metals are the Alkali Metals (Group 1A), and the least reactive nonmetals are the Noble Gases (Group 8A). Krypton is a Noble Gas, Selenium is a Chalcogen, Barium is an Alkaline Earth Metal, and Lithium is an Alkali Metal.

Step-by-step explanation:

The family names for the most reactive metals and the least reactive nonmetals are as follows: i) The most reactive metals are the Alkali Metals, which belong to Group 1A of the periodic table. ii) The least reactive nonmetals are the Noble Gases, located in Group 8A of the periodic table. Therefore, the correct answer is a) Alkali Metals, Noble Gases.

• Krypton is a Noble Gas.
• Selenium is a Chalcogen, also known as a member of Group 6A.
• Barium is an Alkaline Earth Metal, from Group 2A.
• Lithium is an Alkali Metal, from Group 1A.
