Hydrogen has properties similar to:
Correct answer: C. Both a & b
- A. Alkali metals
- B. Halogens
- C. Both a & b
- D. None of these
Explanation
Hydrogen (H) has properties that are similar to both the alkali metals and the halogens. Like the alkali metals, hydrogen has a single electron in its outermost shell and can lose this electron to form a positive ion. Like the halogens, hydrogen can also gain an electron to form a negative 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.
