Question

Why are transition metals less electropositive than S block elements?

Answer 1

Explanation:

Consequently, they have a lesser attraction power from the nucleus, whereas, the corresponding transition metals of the same period have more protons interacting with electrons at the same distance, far from the nucleus as the alkali metals

Answer 2

Transition metals are less electropositive than S block elements because:

• Metals are electropositive because they give electrons and acquire a positive charge.
• Transition elements have small sizes and high nuclear charges which prevent them to isolate or releasing one electron. so, block elements are larger as compared to transition elements. so, metals of transition elements are less electropositive
• Transition metals form a large number of complexes due to their these properties.
• S block elements are strong reducing in nature. reducing properties increases down the group.
