How many energy levels are there in an atom of the element boron? How to determine the number of energy levels in an atom by the power of the periodic system?

Periodic table of elements D.I. Mendeleev helps to find out the features of the structure of the atoms, the elements in it, as follows:

– the serial number is equal to the charge of the nucleus, the number of protons in it and the number of electrons;

– the number of the period is equal to the number of energy levels;

– the group number shows the number of electrons in the last level.

This means that in order to find out the number of energy levels in the boron atom (B), you need to look in what period it is located – this is an element of 3 periods, which means that it has 3 energy levels.
