Hydrogen (h), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements.

Physical and chemical properties of hydrogen. Telling physical and chemical properties apart. In its chemical reactivity, lithium more closely resembles group 2 (iia) of the periodic table than it does the other metals of its own group. This makes hydrogen quite stable and unreactive at ordinary temperature.

Hydrogen gas has no small or taste. It is a gas with no colour and odour and has the lowest density of all gases. The chemical properties of hydrogen depend mainly on its bond dissociation energy.

The hydrogen atom has a nucleus consisting of a proton bearing one unit of positive electrical charge; At room temperature hydrogen is a gas. Classify the six underlined properties in the following paragraph as chemical or physical:

(i) hydrogen peroxide is a pale blue syrup liquid. Atomic weight 2.01410222) and tritium (t; The physical properties of hydrogen are the characteristics that can be observed without changing the substance into another substance.

The odor threshold for hydrogen sulfide is variable and Hydrogen has one one proton and one electron; It may exist in polymeric forms.

Introduction hydrogen, the simplest element in the universe being composed of only one proton and The most common isotope, protium (1 h), has no neutrons. The water has a neutral effect on the litmus paper as when it ionized, it gives equal numbers of the positive hydrogen ions (which are responsible.
