There are no similarities. Noble gases (group 18 elements) have completely filled orbitals with stable electron configuration and are generally unreactive. Alkali metals (group 1 elements) have one valence electron. They are reactive. When these lose one electron, they form ions which has the electronic configuration of the nearest noble gas.
there are none; except for the fact that when alkali metals lose one electron, they achieve the electronic configuration of noble gas.
If alkali metals loses one electron, they achieve the electronic configuration of the nearest noble gases.
alkali metals
Noble gases have larger atomic radii than alkali metals in the same period.
Alkali metals are group 1 elements with one valence electrons. They tend to lose 1 electron and attain stability by forming cations. They are hence chemically reactive. Noble gases are group 18 elements. They have completely filled orbitals and hence are chemically inert.
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
If alkali metals loses one electron, they achieve the electronic configuration of the nearest noble gases.
