Francium has 87 protons and 87 electrons.
Chromium has 24 protons and francium has 87 protons.
The largest atom is francium and has 87 protons and 87 electrons.
If this atom has 43 electron it must have 43 protons to be a neutral atom of no charge.
There is no such atom as Radium 87 - it is Radium 88 and thus has 88. Francium is 87.
A neutral atom with 49 protons has 49 electrons.
Cobalt has 27 protons and francium has 87 protons; 87-27=60.
The largest atom is calcium which has 4 shells.
Francium has one valence electron.
An atom typically consists of three main particles: protons, neutrons, and electrons. Protons and neutrons reside in the nucleus, while electrons orbit around the nucleus. The number of protons determines the atom's identity, while the total number of protons and neutrons in the nucleus gives the atom's mass number.
Protons won't be found in an electron shell. They are concentrated in the nucleus.
Francium has seven electron shells; electrons per shell: 2, 8, 18, 32, 18, 8, 1.
An Ion is:either positive ion that is a neutral atom with an electron or more stripped off from its electron orbits, ora negative ion that is a neutral atom acquiring an electron or more to its electron orbits.Accordingly, the number of protons in the nucleus is not affected by the ionization process. The number of protons in any ion of an element is the same number corresponding to the atom structure of the atom of that element.
