(ii) In d-block series, the elements near alkaline earth metals are more electropositive than the rest of the members.
(iii) Metalloids are less electropositive than metals.
(iv) Halogens (non-metals) are least electropositive. In halogen group, electropositive character increases as atomic number increases.
