q1 - find the alkali metal in the 4th period\nphosphorus\noxygen\npotassium\nchlorine\nquestion 2 (1 point)\nq2 - find the halogen in the 3rd period\npotassium\noxygen\nchlorine\nphosphorus

Answer

Brief Explanations:

  • For Q1, alkali metals are in Group 1 of the periodic table. Potassium is in the 4th period and Group 1. Phosphorus is a non - metal in Group 15, Oxygen is a non - metal in Group 16, and Chlorine is a halogen in Group 17.
  • For Q2, halogens are in Group 17 of the periodic table. Chlorine is in the 3rd period and Group 17. Potassium is an alkali metal, Oxygen is a non - metal in Group 16, and Phosphorus is a non - metal in Group 15.

Answer:
