Which statement is correct:

Correct answer: A. Hydrogen resembles in properties with IA, IVA and VIIA elements

  • A. Hydrogen resembles in properties with IA, IVA and VIIA elements
  • B. Hydrogen resembles in properties with IIIA, IVA and VA elements
  • C. Hydrogen resembles in properties with IIA, IVA and VIA elements
  • D. Hydrogen resembles in properties with IIA, IIIA and VIIA elements

Explanation

Hydrogen's placement at the top of Group IA is due to its similarity in properties with alkali metals, such as having one electron in its outer shell that it can lose to form ions, despite being a nonmetal. Additionally, its resemblance to halogens, such as forming stable diatomic molecules and hydride ions, also justifies its placement at the top of Group VIIA.

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.
