What is the name of the alkali metal that is in period 4

What is the name of the alkali metal that is in period 4?
What is the name of the halogen that is in period 4?
What is the name of the alkaline earth metal that is in period 6?
What is the name of the noble gas that is in period 1?

The Correct Answer and Explanation is :

The answers to your questions are as follows:

  1. The alkali metal in Period 4: Potassium (K)
  2. The halogen in Period 4: Bromine (Br)
  3. The alkaline earth metal in Period 6: Barium (Ba)
  4. The noble gas in Period 1: Helium (He)

Explanation:

  • Alkali Metals: The alkali metals are found in Group 1 of the periodic table. They are highly reactive and are known for their ability to form basic hydroxides when combined with water. In Period 4, the alkali metal is potassium (K). Potassium has an atomic number of 19 and is a soft, silvery-white metal. It is essential for the proper functioning of living organisms and plays a critical role in nerve function and fluid balance.
  • Halogens: Halogens are found in Group 17 of the periodic table and are highly reactive nonmetals. In Period 4, the halogen is bromine (Br). Bromine is a reddish-brown liquid at room temperature and is used in a variety of industrial processes, including flame retardants and in the manufacture of certain medicines. It has an atomic number of 35.
  • Alkaline Earth Metals: These metals are found in Group 2 of the periodic table and are known for their ability to form alkaline hydroxides. In Period 6, the alkaline earth metal is barium (Ba). Barium is a soft, silvery-white metal and has an atomic number of 56. It is commonly used in the oil and gas industry for well drilling and in the production of fireworks.
  • Noble Gases: Noble gases are located in Group 18 of the periodic table and are known for their lack of reactivity due to having a full complement of electrons in their outer shell. The noble gas in Period 1 is helium (He). Helium is a colorless, odorless, and non-reactive gas, often used in balloons and as a coolant in various industrial applications. It has an atomic number of 2 and is the second lightest element in the universe.
