19. name the element represented by the orbital diagram below.\n20. name the element represented by the orbital diagram below.

Answer

Explanation:

Step1: Count electrons in first question

1s has 2 electrons, 2s has 2 electrons, 2p has 6 electrons, 3s has 2 electrons, 3p has 6 electrons, total is 18 electrons.

Step2: Identify element for first question

The element with 18 electrons is Argon (Ar).

Step3: Count electrons in second question

1s has 2 electrons, 2s has 2 electrons, 2p has 6 electrons, 3s has 2 electrons, 3p has 6 electrons, 4s has 2 electrons, 3d has 10 electrons, 4p has 6 electrons, 5s has 2 electrons, 4d has 10 electrons, 5p has 3 electrons. Total is 49 electrons.

Step4: Identify element for second question

The element with 49 electrons is Indium (In).

Answer:

  1. Argon (Ar)
  2. Indium (In)
