Which of the following statements is correct? a. All metals are ductile. b. All non-metals are ductile. c. Generally, metals are ductile.

Metals Non–metals 1. Metals can lose electrons easily. 1. Non-metals cannot lose electrons easily. 2. Metals cannot gain electrons easily. 2. Non-metals can gain electrons easily. 3. Metals generally form ionic compounds. 3. Non–metals generally form covalent compounds. 4. Metals...

(c) either metals or non-metals 

This element is a metal. Other characteristics expected to be possessed by the element are–lustre, malleability, heat and electrical conductivity. 

(a) Iodine  (b) Bromine  (c) Graphite  (d) Carbon  (e) Sulphur, phosphorus  (f) Oxygen

(a) False as non metallic oxides are acidic in nature.  (b) True  (c) False as in a displacement reaction more reactive element displaces less reactive metal from its salt.  (d) False as Coal...

Metallic solids are electrical conductors, malleable, and ductile. 

It is because HNO3 is a strong oxidising agent. It oxidises the Hq produced to H2O and itself get reduced to any of the oxides of the nitrogen, like NO2, NO,...

(i) This is due to d-d transition. When visible (white) light falls on a transition metal compounds, they absorb certain radiation of visible light and transmit the remaining ones. The...

(i) This is due to presence of unpaired electrons in the (n–1) d orbitals of transition elements. (ii) The chemistry of actinoids is not as smooth as lanthanoid because they are...
