There is no such element. Atomic numbers represent how many protons are in the nucleus of an atom. Lithium's atomic number is three; it has three protons. An atom with 35.543 protons can't exist because there can't be a fraction of a proton - how can you have 35 and .543 protons? I think perhaps you confused atomic number with Atomic Mass. Chlorine's atomic mass is 35.543 grams.
It is Bromine.
Bromine
bromine
Bromine is the name of the element that is a liquid halogen. Bromine has the chemical symbol Br, and it has the atomic number of 35.
The element with the atomic number 17 is Chlorine (Cl).
If an atom has 35 electrons, it will also have 35 protons and its atomic number will be 35. If you go to the periodic table an look up the element with atomic number 35 you will se it is the element Bromine and the symbol for the element is Br.
Atomic number = Number of protons = 35 - 18 = 17.So the element is chlorine.
An atom's atomic number tells us the amount of protons it has. If that atom is to remain neutral, it must also have the same number of electrons. Arsenic's atomic number is 33. Thus, it has 33 protons and 33 electrons.
