Given `r_(n+1)-r_(n-1)=2r_(n),`where `r_(n)-r_(n-1)=r_(n+1),` are Bohr radius for hydrogen atom in `n^(th),(n-1)^(th)` shell respectively. Calculate the value of n.

Given that r_(n-1)+r_(n)=r_(n+1) where r represents Bohr's orbit for (n-1)^("th"),n^("th") and (n+1)^("th") orbit, then n is

Difference between n^(th) and (n+1)^(th) Bohr's radius of H atom is equal to it's (n-1)^(th) Bohr's radius. The value of n is

The radius of n^th orbit r_n in the terms of Bohr radius (a_0) for a hydrogen atom is given by the relation

Given in hydrogen atom r_(n),V_(n),E,K_(n) stand for radius, potential energy, total energy and kinetic energy in n^(th) orbit. Find the value of U,v,x,y. {:((A),u=(V_(n))/(K_(n)),(P),1,),((B),(1)/(r_(n))propE^(x),(Q),-2,),((C),r_(n)propZ^(y),(R),-1,),(,(Z="Atomic number"),,,),((D),v=("Orbital angular momentum of electron"),(S),0,),(,("in its lowest energy"),,,):}

If 1<=r<=n, then n^(n-1)C_(r)=(n-r+1)^(n)C_(r-1)

If (n+r)(n+r-1)=110and(n-r)(n-r-1)=20 solve for n and r

If ^(n)P_(r)=^(n)P_(r+1) and ^(n)C_(r)=^(n)C_(r-1, then the ) value of n+r is.

If .^(n+1)C_(r+1):^(n)C_(r):^(n-1)C_(r-1)=11:6:3 , find the values of n and r.
