The four lines observed in the visible emission spectrum of hydrogen ell us that a. Only certain energies are allowed for the electron in a hydrogen atom b. We could observe more lines if we had a stronger prism c. The hydrogen molecules they came from have th d. e formula H4 There are four electrons in an excited hydrogen atom According to the Bohr model, when a hydrogen electron makes a transition from n 4 to ne2, which of the following statements is true? l. Energy is emitted. Il. Energy is absorbed. IIl Electrons lose energy IV. Electrons gain energy a. I and IV b. Il and IV c. I only d. I and lIl Solution 1. the four lines observed in the visible emission spectrum of hydrogen tell us that only certain energies are allowed for the electron in a hydrogen atom because these are lines which allow only certain frequencies Hence option (a) is correct 2. When an electron jumps from higher orbital to lower orbital the energy is emitted and electrons loose energy. Hence option (d) is correct . .
