An electron shell can hold 2(n^2) electrons (technically) where n is the shell number, i.e. shell 1 can hold 2, shell 2 can hold 8, 3 holds 18 and so on.
The atomic number of Nitrogen is 7, i.e. it has 7 electrons (to match its 7 protons, assuming it isn't an ion).
With the atomic number, you simply start from shell 1 and work out. So we put 2 electrons in shell 1, leaving us with 5 left. Shell 2 can hold 6 so we can fit all 5 in.
In other words, you should have 2 electron shells on the atom, shell 1 with 2 e- and shell 2 with 5 e-.
"Most gets converted to heat energy" is the one among the following choices given in the question that describes what <span>happens to the energy put into a machine that does not get used to do useful work. The correct option among all the options that are given in the question is the second option or option "B". I hope it helps you.</span>
Work Done = Force * Distance
This means the least work is exerted by the most distance, so the longer ones are less likely to break.
The shortest one will be the one that breaks easiest.
