Question

Q.no.5 write the correlation for Second pair 1. Mercury: Metal :: Carbon

Answer 1

Mercury : Metal :: Carbon : Non-metal

Explanation:

Elements are differentiated into metals, non-metals and metalloids. Metals have certain physical and chemical properties like:

Metals: Malleable and ductile, shiny and lustrous, form electropositive ions, are donor atoms, conduct electricity.

Mercury

• Metals are generally in crystalline solid form but as an exception, Mercury is a liquid metal at room temperature.
• It is a heavy silvery liquid.
• Mercury has an atomic number of 80 and belongs to group 12 and period 6 of periodic table.

NON-METALS: Amorphous and dull in appearance, have low density and are poor conductors of heat and electricity, form electronegative ions and are acceptor of electrons.

Carbon

• Carbon is a non-metal with an atomic number of 6 and belongs to group 14 of the modern periodic table.
• It has four valence electrons in its outermost shell and forms covalent bonds with other elements.
• Carbon in its pure form exists as graphite or diamond. Graphite is a non-metal but still conducts electricity.
