Am (Americium) and U (Uranium) both radio active.
Ne (Neon) is an inert/noble gas.
K (Potassium - latin ;Kalium) is not radioactive.
No, AR-40 cannot change back to K-40. Ar-40 is a stable isotope of Argon, while K-40 is a radioactive isotope of Potassium. Ar-40 is formed from the decay of K-40, but once it is formed, it will not transform back into K-40.
Potassium (K) is a metallic element. It belongs to Group 1 of the periodic table, also known as the alkali metals. Metallic elements tend to lose electrons to form cations, which is the case with potassium.
K (lowest) Na Li B N (highest)
Both elements, sodium (Na) and potassium (K) lie in the Group 1 column of the Periodic Table , which contains the members of the Alkali Metals family. Members within a family, or column, of elements tend to have similar chemical properties.
The number of elements in set ( n^2 ) depends on the set ( n ). If ( n ) is a set with ( k ) elements, then ( n^2 ) will have ( k^2 ) elements.
These are the alkali metals; the radioactive one is francium (Fr).

I think it's the elements of the Periodic table. He, Ne, Ar, Kr, Xe, Rn

Woh kia cheez hai k Jis ne kharida us ne pehna nahin aur jis ne pehna us ne dekha nahin?
K selected populations tend to live in stable, predictable environments.
u can memorize periodic table elements in this way. for example the elements of alkali metals : Hi Laila Ne Ki Rub Se Fryad. (H,Li,Na,K,Rb,Cs,Fr)
Potassium (K) is a metallic element. It belongs to Group 1 of the periodic table, also known as the alkali metals. Metallic elements tend to lose electrons to form cations, which is the case with potassium.
Potassium and Neon are elements and hence don't have any chemical formula. Their chemical symbols are P and Ne respectively.
Chemical elements have chemical symbols not a formula. Examples: Ne, C, Ir, Fe, Zr, U, Pu, K, Na, Au, Sr, Mg, Ca, Li, Tc, Am, No, Rn, Ra, Th, B etc.
