The element Mercury (Hg) has 80 protons and 80 neutrons. It exists in several different isotopes which have different numbers of neutrons, however, the average number of neutrons in a mercury atom is 121. (The atomic weight is 200.59 which would require 80 protons and 120.59 neutrons, although of course every atom has only whole numbers of neutrons, you only get fractions because you are getting an average of different isotopes.)
80 eloctrons are present is a Hg atom
80 protons
There are 18 protons in an Aragon atom.
An Carbon Atom has an total of 6 protons.
Based on the atomic number of lithium there are three protons in a lithium atom.
The proton! The number of protons in an atom's nucleus is the "ID card" of that atom. If an atom has 6 protons, it's carbon. If it doesn't have 6 protons, it's not carbon. Simple as that!
There can be between 124 and 136 particles (neutrons and protons) in the nucleus of a xenon atom.
The symbol of Bromine is Br and number of protons(or atomic number) which is also equal to the number of electrons is 35
There are 18 protons in an Aragon atom.
An atom of copper has 29 protons.
There are 26 protons in the atom of iron.
An atom of chlorine has 17 protons.
there are 12 protons in an atom of magnesium:-)
Chlorine has 17 protons.
there are 7 protons in each nitrogen atom.
That would depend on how many protons exist in the nucleus of the atom. An atom with 6 protons is a carbon atom; 7 protons is nitrogen, and 8 = oxygen.
An Carbon Atom has an total of 6 protons.
There are 14 protons in one atom of Silicon
It depends on what atom it is, the number of protons in the nucleus of an atom or ion defines what type of atom it is.
