Choose the correct statement:
  • a)
    Across a period electropositivity of elements increases
  • b)
    Across a period basic nature of oxides increases
  • c)
    Across a period acidic nature of oxides increases
  • d)
    Across a period metallic character increases
Correct answer is option 'C'. Can you explain this answer?

Answers

The non metallic character decreases down the group.And we know the oxides of non-metal r acidic in genral.Hence acidic character of oxides decreases down d group. Down the group the size of the element increases, electronegativity decreases ,metallic character increases and hence the acidic character decrease.

The non metalliccharacter decreasesdown the group.And we know theoxidesof non-metal racidicin genral.Henceacidic character of oxides decreasesdown d group. Down the group the size of the elementincreases, electronegativity decreases,metalliccharacter increasesand hence theacidic character decrease.
