<span>the noble gases are those who occupy the eighth group of the periodic table and are so called because having the complete valence shell do not need to form bonds with other atoms and are thus in atomic form ...
</span>
The noble gases (also called rare gases) are of the inert gases that constitute the eighteenth [1] group of the periodic table of the elements, ie, the right-most column. They consist of atoms with electron shells full. It includes the following elements: helium neon argon krypton xenon radon Ununoctium <span>Sometimes they (particularly helium) are located together with other gases (mostly nitrogen and methane) into endogenous sources; helium of endogenous origin comes from the decomposition of radioactive elements present in the subsurface that emit α particles (ie ions He2 +): These oxidized species present in the soil and become elio.I atoms of the noble gases are all monatomic gas, not easily liquefiable, present the atmosphere in different percentages; the most common is argon which is approximately the 0.932%.</span>
<span>The correct answer among
the choices given is the last option. Galaxies are classified according to
their shapes or visual morphology. There three main types of galaxies
currently. They are the elliptical, spiral and irregular. Elliptical galaxies
are like a spheroid or an elongated sphere. Spiral galaxies are characterized
and distinguished by having a bulge, a disk and a halo. Lastly, irregular
galaxies do not have regular or symmetrical shape.</span>
