  1. Question 1

    Q1. Hydrogen is tricky on a wall chart. Which statement matches how hydrogen is usually classified in broad introductory periodic discussions?

    • A) Hydrogen is a nonmetal placed above Group 1 but it is not a typical alkali metal in behaviour
    • B) Hydrogen is always grouped with the halogens because it always forms H+ in every compound
    • C) Hydrogen is a transition metal because it can lose electrons
    • D) Hydrogen is a noble gas because it is the smallest atom

    Answer: Hydrogen is a nonmetal placed above Group 1 but it is not a typical alkali metal in behaviour

    Explanation: Hydrogen is a nonmetal that is conventionally placed above Group 1 on the periodic table because it has one valence electron, yet it does not share the typical alkali-metal properties such as being a soft, lustrous, reactive solid at room temperature.
