Question

pls do ans this fast its urgent​

Answer 1

Explanation:

1) r =o.529*n^2\z

R1 = radius of bohr orbit ,when n=1

R1=0.53*1^2\1

R1=0.530 angstrom

when n=2,

R2=o.530*2^2\1

R2=0.530*4

R2=2.12 angstrom

2) uncertainity in Position of electron( Xe)=uncertainity in position of helium (Xh)

uncertainity in momentum of electron (pe)= 5*10^-26 Kg ms^-1

(Ph)=?
