is it hydrogen.
if yes...
•
hydrogen has the atomic number 1, and has 1 electron and 1 proton;
•
the atomic mass of hydrogen is 1.00795. There are 3 isotopes with the mass numbers of 1, 2, 3. Their properties are very different, as even increasing mass by one means a double increase for hydrogen;
•
as it has only 1 electron in the outer level, hydrogen displays both oxidative and reductive properties. After it gives its electron, hydrogen is left with a free orbital, which takes part in the formation of chemical bonds according to a donor-acceptor mechanism;
•
hydrogen is a strong reducer, and so in the first group of the main sub-group this element leads the alkaline metals as the most active;
•
in interaction with strong reducers (for example metals), hydrogen becomes an oxidizer, receiving an electron. These compounds are called hydrides. For this property, hydrogen leads the sub-group of halogens, with which it shares similarities;
•
the low atomic mass makes hydrogen the lightest element. The density of the element is low, so hydrogen is called a standard of lightness.
Hydrogen is a unique chemical element that does not resemble any of the others, with special properties of enormous significance and importance.
Physical properties of hydrogen
Hydrogen has the following physical parameters:
•
melting temperature — (-259.2) degrees Celsius;
•
boiling temperature — (-252.76) degrees Celsius;
•
in this interval, hydrogen is a colorless liquid without any smell;
•
at high pressure, snow-like crystals of solid hydrogen form;
•
in special conditions, hydrogen is capable of moving to a metal state;
•
hydrogen is insoluble in water, so it can be obtained in the laboratory by the water displacement method;
•
in ordinary conditions, hydrogen is a colorless gas without any smell or taste. It is a combustible and explosive substance;
•
it dissolves well in metals because of its ability to diffuse through their thickness;
•
hydrogen is 14.5 times lighter than air;
•
the crystal structure of the simple substance is molecular, and the bonds are weak, which means it breaks down easily.
