Best position of hydrogen in the periodic table is above I. Group which is mainly due to
Correct answer: B. Similar outer most shell electronic configuration
- A. Both are electropositive
- B. Similar outer most shell electronic configuration
- C. Both form ionic compounds
- D. All
Explanation
Hydrogen, with its single electron in the 1s orbital, shares similarities with Group 1 (IA) elements in terms of outer shell configuration. Similar to alkali metals like sodium (1s²2s¹), hydrogen readily loses its single electron to achieve a stable octet configuration, exhibiting similar chemical behavior.

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.
