Element Properties: 1-7 atomic number

MIRAMAR, Fla. - March 24, 2021 - PRLog -- HYDROGEN
Atomic symbol: H
Atomic weight: 1.00794
Atomic number: 1
Hydrogen is a colorless, odorless, tasteless gas that can be flammable or explosive when mixed with air, oxygen, and chlorine. Hydrogen is not very reactive at room temperature, but at higher temperatures it burns vigorously and often explosively in air or oxygen to form water. In the presence of a catalyst and under pressure, hydrogen will combine with vegetable oils to form solid fats used as shortening, in a process known as hydrogenation.

HELIUM
Atomic symbol: He
Atomic weight: 4.002602
Atomic number: 2
Helium is a colorless, odorless, tasteless, nonflammable, monatomic inert gas. It is obtained from natural gas deposits by liquefying all other constituents and collecting the helium. The percentage obtained from these deposits may range from 1% to 2%.

LITHIUM
Atomic symbol: Li
Atomic weight: 6.941
Atomic number: 3
Lithium is a silvery white metal that turns yellow when exposed to moist air. When heated sufficiently, it emits light radiation that is red in color. Lithium is a good electron source in photoelectric cells and cyclotrons.

BERYLLIUM (https://www.edge-techind.com/category/Beryllium-Be-131-1....)

Atomic symbol: Be
Atomic weight: 9.012182
Atomic number: 4
Beryllium is very rare, its pricipale ore is beryl, a complex aluminosilicate. When beryl has traces of chromium impurities, it is emerald. When beryl contains traces of iron, its aquamarine. Beryllium does not occur free in nature, and is primarily used in alloys—especially copper to form non- sparking tools.

BORON (https://www.edge-techind.com/category/Boride-Ceramic-91-1...)
Atomic symbol: B
Atomic weight: 10.811
Atomic number: 5
Boron is relatively rare, and always found combined with oxygen in borates. It is extremely hard and brittle, and is found in two allotropic forms—crystalline and amorphous. Boron is used in flares to give off a green color, as an igniter in rockets, as filaments in aerospace structures, and in silicon semiconductors to improve conductivity.
CARBON (https://www.edge-techind.com/category/Carbide-Ceramic-87-1.html)
Atomic symbol: C
Atomic weight: 12.0107
Atomic number: 6
Electron configuration: 2-4
Oxidation states: +2, ±4
State of matter: solid
Carbon is found free as the mineral graphite or as diamonds. It is essential to all animal and plant life. Graphite found in large crystals is mined, or obtained by heating coke and pitch in furnaces at very high temperatures. Volatiles are driven off and large graphite crystals then grown in the furnace.

NITROGEN (https://www.edge-techind.com/category/Nitride-Ceramic-86-1.html)

Atomic symbol: N
Atomic weight: 14.00674
Atomic number: 7
Boils at -195.8°C, melts at -209.86°C
Notes: Nitrogen is an odorless gas, usually obtained by the fractional distillation of liquid air. The process of including nitrogen to combine chemically with other substances is known as the fixation of nitrogen. A lot of nitrogen is used in the fixation process, which produces the raw materials for fertilizers, explosives, drugs, and dyes.
