Which of the following is not a very hard metal?(a) Chromium(b) Molybd

1.	Which of the following is not a very hard metal?(a) Chromium(b) Molybdenum(c) Tungsten(d) ZincI got this question by my school principal while I was bunking the class.The query is from General Properties of the Transition Elements (D-Block) topic in section D and F-Block Elements of Chemistry – Class 12
Answer» Correct choice is (d) Zinc To explain: Greater the NUMBER of unpaired electrons, STRONGER is the bonding due to overlapping of unpaired electrons between different metal atoms. CR, MO and W have maximum unpaired d-electrons and are harder metals whereas Zn, Cd and Hg are not very HARD due to the absence of unpaired electrons.
