Which of the following is the value for Rydberg constant?(a) 2.95 x 10

1.	Which of the following is the value for Rydberg constant?(a) 2.95 x 10^-18 J(b) -2.95 x 10^-18 J(c) -2.18 x 10^-18 J(d) 2.18 x 10^-18 JThis question was addressed to me in an online quiz.My question is taken from Bohr’s Model for Hydrogen Atom topic in division Structure of Atom of Chemistry – Class 11
Answer» RIGHT choice is (c) -2.18 x 10^-18 J Easiest explanation: The energy of an nth orbit in a hydrogen ATOM is given by the FORMULA En = -RH/n^2, where is the energy of nth orbit and RH is the Rydberg CONSTANT. When experiments were conducted, the product of the energy of nth orbit to the SQUARE of n is constant i.e. Rydberg constant.
