Hydrogen has only one electron in its only (and outer) electron shell. if a hydrogen atom were to absorb a tremendous amount of energy where would bohr say the electron would go?
a. fly off the atom
b. nowhere, it would just speed up.
c. spiral inwards towards the nucleus
d. move up to another shell that would form

The correct answer is option D, that is, move up to another shell that would form.

Explanation:

An atom comprises neutrons, protons, and electrons. The neutrons and protons are located in the nucleus and the electrons orbit the nucleus in their fixed shells. The jumping of the electron takes place to its higher shell when it acquires some form of energy, and can move to the lower shell when it loses some energy. Therefore, as mentioned in the given question, when a single electron gains a small amount of energy, then it should jump to another higher shell.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
