The energy capacity of an atom of some element is 35 electrons. How many protons are there in the nucleus of an atom?

The energy capacity of an atom of some element is 35 electrons. How many protons are there in the nucleus of an atom? Indicate the serial number of the element and its name. Create an electronic formula.

The serial number of the element in the PS:
– core charge
-number of protons in the nucleus
– the number of electrophones in an atom
Based on this information, the number of electrons is equal to the number of protons = 35
Element with atomic number 35 in Mendeleev’s PS – bromine (Br)
Electronic formula – 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5
