1.	Assume that the electron in He + ion is excited to the second orbit (n = 2). Calculate the following: (i) the radius of the orbit (ii) the velocity of the electron (iii) the potential energy of the electron, and (iv) the kinetic energy of the electron
Answer» 12x10^(-10)(n^2/Z) metren is ORBIT no. z is atomic number.here, n=2, z=2v=2.18X10^6(z/n) ms^(-1)E=31.6 (Z^2/ n^2) ev(ELECTRON volt)POTENTIAL energy= 2Ekinetic energy= -E
