There are five elements in group 5A of the periodic table identify them, and give the period of each Check all that apply. Phosphorus (P) Period 3 Antimony (Sb) Period 5 Tantalum (Ta) Period 6 Niobium (Nb) Period 5 Bismuth (Bi) Period 6 Oxigen (0) Period 2 Arsenic (As) Period 4 Nitrogen (N) Period 2 Vanadium (V) Period 4

The Correct Answer and Explanation is :

The correct elements in Group 5A (also known as Group 15 or the nitrogen group) of the periodic table are:

  1. Nitrogen (N) – Period 2
  2. Phosphorus (P) – Period 3
  3. Arsenic (As) – Period 4
  4. Antimony (Sb) – Period 5
  5. Bismuth (Bi) – Period 6

Explanation:

Group 5A of the periodic table consists of elements with five valence electrons in their outermost shell, which places them in the p-block. These elements show a combination of metallic, metalloid, and nonmetallic properties.

  1. Nitrogen (N) is a nonmetal in Period 2. It is the lightest element in this group and plays a vital role in biological systems as a key component of amino acids and nucleotides.
  2. Phosphorus (P) is a nonmetal in Period 3. It exists in various allotropes, such as white, red, and black phosphorus, and is essential in biological processes like DNA and ATP formation.
  3. Arsenic (As), found in Period 4, is a metalloid, meaning it has properties of both metals and nonmetals. It is commonly found in semiconductors and is toxic in high concentrations.
  4. Antimony (Sb), in Period 5, is also a metalloid. It is used in alloys to increase strength and in flame retardants due to its chemical stability.
  5. Bismuth (Bi), in Period 6, is a metal and the heaviest element in the group. It is known for its low toxicity compared to other heavy metals and is used in medical and cosmetic applications.

Misclassified Elements:

  • Tantalum (Ta) and Niobium (Nb) belong to Group 5 (transition metals), not Group 15.
  • Vanadium (V) is in Group 5 (transition metals), not Group 15.
  • Oxygen (O) is in Group 6A (Group 16), not Group 15.

This highlights the importance of correctly identifying elements based on their group and period properties.
