When hydrogen loses its electron to form H+ion then it resemble:
Correct answer: C. Alkali metals
- A. Transition metals
- B. Halogen
- C. Alkali metals
- D. Noble gases
Explanation
Alkali metals are group 1A elements so they have one eletron in valence shell which they easily lose and form positive ion so hydrogen which has only one electron also loses it and becomes H+ ion

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
