Question

Select all the true statements.

The highest oxidation state of elements in Groups 3A through 7B is +3.

  

First ionization energy values generally increase down a transition group.

  

The transition elements in a period show a steady increase in electronegativity.

In the transition series, atomic size across a period decreases at first but then remains relatively constant.

Ionic bonding is more prevalent for the higher oxidation states and covalent bonding is more prevalent for the lower states.

Answer 1

Two statements are correct :

1) First ionization energy values generally increase down the group.

2) The transition elements in a period show a steady increase in Electronegativity.

All other statements are incorrect.

ionic bond is more prevalent in low oxidation state and covalent bond in high oxidation state.

In transition elements, atomic size in across a period decreases then become constant then increases.

The highest oxidation state of elements in group 3A through 7B is +7.
