WebMixtures of hydrogen and oxygen react at a measurable rate only above 300° C, according to the equation 2H 2 + O 2 → 2H 2 O. Such mixtures containing 4 to 94 percent hydrogen ignite when heated to 550°–600° … WebImgur. The energy of the electron of a monoelectronic atom depends only on which shell the electron orbits in. The energy level of the electron of a hydrogen atom is given by the following formula, where n n denotes the principal quantum number: E_n=-\frac {1312} {n^2}\text { kJ/mol}. E n = − n21312 kJ/mol. For a single electron instead of ...
