How many protons does the largest element atom have on the periodic table?
The largest atom is francium and has 87 protons and 87 electrons.
How many protons do chromium and francium have?
Chromium has 24 protons and francium has 87 protons.
How many protons are in an atom which has 55 neautrons and 43 electons?
If this atom has 43 electron it must have 43 protons to be a neutral atom of no charge.
How many protons does radium 87 have?
There is no such atom as Radium 87 - it is Radium 88 and thus has 88. Francium is 87.
How many electrons in an atom with 49 protons?
A neutral atom with 49 protons has 49 electrons.
How many more protons does francium have in its nucleus than cobalt?
Cobalt has 27 protons and francium has 87 protons; 87-27=60.
How many protons can fit in the third shell of a regular atom?
Protons won't be found in an electron shell. They are concentrated in the nucleus.
How many valence electons does francium have?
Francium has one valence electron.
How many protons are there in the ions?
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.
What charge does the electron cloud of every atom have?
In a neutral atom, the charge on the electron cloud is balanced by the carge on the atom's nucleus. The nucleus has a positive charge proportional to the number of protons in it. This attracts and holds the negatively charged electrons in the electron cloud. And in a neutral atom (not an ion), there will be as many electrons in the electron cloud as protons in the nucleus. The charges will balance.
How many protons and neutrons in francium?
Francium has 87 positively charged protons and 87 negatively charged electrons, plus a varying number of uncharged neutrons, of which 136 is the commonest amount. Number of neutrons = Atomic mass of the isotope - 87
What do you know about the numbers of protons and electrons in an atom?
The number of protons defines what element the atom is, and it also defines how many electrons the atom has in its various orbitals in a normal state.There is one electron per proton in an atom in a normal state.
