Also, many periodic tables have a stair-step line on the table identifying the element groups. Question 4 (00000001A0105103, Variation No. Answer 1):- a):- Chromium is a metal because it is electro-positive, malleable, ductile, hard, lustrous, sonorous and good conductor of heat and electricity. Ionic bonds form when there is a transfer of electrons . Chemical procedures, on the other hand, can break down these compounds into individual elements. Elements of the periodic table are grouped as metals, metalloids or semimetals, and nonmetals. This type of classification is based on the shared physical and chemical properties. No sharp line can be drawn between the metals and nonmetals, and certain elements partake of both acid and basic qualities, as chromium, manganese, bismuth, etc. Before then, it had been used in dyes and paints . gold, copper, oxygen, chlorine, diamond, etc. Chromium is a chemical element with the symbol Cr and atomic number 24. Problem 37 Easy Difficulty. Compounds, on the other hand, are pure entities formed by the chemical combination of two or more elements in a predetermined ratio.
