Xenon is a non-metal element, belonging to group 18 of the periodic table. The elements found in group 18 of the periodic table are called the noble gases. What is an example of a xenon? An example of a use of xenon is in sunbed, or tanning bed lamps. Other uses include in lasers...
ammonium salts, as well as nitrogen oxides andnitric acid(the latter substances being formed in electrical storms and in the internal combustion engine). Free nitrogen is found in many meteorites; in gases of volcanoes, mines, and some mineral springs; in the Sun; and in some stars and ...
John Newlands compared elements to musical notes with his law of octaves. As on a scale, every eighth element would share similar properties when arranged by increasing atomic weight. Newlands did not account for exceptions, however, and it was only upon establishment of the Periodic Table that...
Helium is one of thenoble gases or inert gases, which means it has a complete electron valence shell so it's not reactive. Unlike gas ofatomic number 1(hydrogen), helium gas exists asmonatomicparticles. The two gases have comparable mass (H2and He). Single helium atoms are so small they...
