metals, non metals and metalloids questions

Alkali metals are metals while hydrogen is a non-metal..

Non-metals are the elements in groups 14-18 of the periodic table. Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The ..

Oxygen reacts with a number of non-metals to form their respective oxide..

Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gaseous, liquids or..

Dihydrogen reacts with non-metals under specific conditions. Some of the reactions are: The reactivity of halogen towards dihydrogen decreases as: F 2 > Cl 2 > Br 2 > I 2 As a result, fluorine reacts in dark, chlorine in the presence of sunlight, bromine reacts only upon heating whi..

Magnesium combines with non-metals on heating. ..

With hot concentrated nitric acid, non-metals are oxidized to their oxide while the acid itself gets reduced to nitrogen dioxide. In all the reactions described below, the nascent oxygen is released during the thermal decomposition of the acid, which oxidizes the non-metals. ..

When dry chlorine is passed through molten sulphur it combines with sulphur to form vapors of sulphur monochloride S 2 Cl 2 . When these vapors are condensed, they form a red liquid (Fig.14.11)...
