What is the longest wavelength of light that can be emitted by a hydrogen atom that has an initial configuration of 60'?
Enter a wavelength in nm accurate to 3 significant figures.

The nucleus inside an atom consists of positively-charged  protons  and neutrally-charged  neutrons. a  proton  is a subatomic particle with a positive electric charge. allprotons  are identical.

North atlantic current or north atlantic drift is the answer

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
