Properties of Nonmetals
Introduction to properties of non-metals:
At room temperature, over half of the non-metals are gases, except bromine, which is a liquid. The most abundant non-metal in the earth's crust is oxygen, which constitutes about 50% of the earth's crust and along with nitrogen it forms the main constituents of air. The next abundant non metal is silicon which constitutes about 26% of the earth’s crust. Oxygen and silicon are the two major constituents of earth. Hydrogen and oxygen are the two major constituents of the oceans.
In general, the physical properties of the nonmetals are the opposite of those attributed to metals. Nonmetals are often gases at room temperature. The nonmetals that are solids are not lustrous, are not malleable or ductile, and are poor conductors of heat and electricity. Some nonmetals are very reactive, but the nature of the reactions is different from that of metals. Nonmetals tend to gain electrons to form negative ions rather than to lose electrons to form positive ions.
I like to share this Bond Order Equation with you all through my article.
Properties of Non-metals in Deatil:
Physical state
Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (iodine, carbon, sulphur). These have no metallic lustre,( except iodine) and do not reflect light.(Except carbon in the form of diamond).
Nature
Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets. Except- diamond is the hardest substance known.
Conduction
They are poor conductors of heat and electricity. (Except graphite conducts heat, both graphite & gas carbon conduct electricity.)
Understanding Physics Formula Chart is always challenging for me but thanks to all math help websites to help me out.
More Properties of Nonmetals:
Electronegative Character
Non-metals have a tendency to gain or share electrons with other atoms. They are electronegative in character.
Reactivity
They generally form acidic or neutral oxides with oxygen
Melting and Boiling Points
Non-metals have low melting and boiling points.
