WebThe electron’s speed is largest in the first Bohr orbit, for n = 1, which is the orbit closest to the nucleus. The radius of the first Bohr orbit is called the Bohr radius of hydrogen, denoted as a0. Its value is obtained by setting n = 1 in Equation 6.38: a0 = 4πε0 ℏ2 mee2 = 5.29 × 10−11m = 0.529Å. 6.39 WebSep 10, 2024 · Answer: The energy associated with first orbit of He+ is -54.380 eV Explanation: For the first orbit of helium atom, n = 1 and Z= 2 (Atomic number or proton number for helium atom) According to the energy associated formula Now put the value of Z and n in the above formula. dahan full movie download
