The atom discovered with the highest atom number = number of proton = number of electrons
Note that some negative ions might be bigger.
The biggest element so far discovered is 294Uuo (Ununoctium, element 118), a superheavy transactinide element. Only a small number of atoms of this element have ever been produced.
The caesium atom with an empirical radius of 260 pm.

Why does francium have the biggest atomic size?
Francium is located on the bottom left side of the periodic table of elements. Meaning it has the largest number of electron shells and lowest electron negativity. Thus having the biggest atomic size.
How do you know which one is the atomic number?
It is usually the biggest number in each elements box otherwise it is the number that is next in line from the one in front or behind the next element
Why is francium the most explosive element on the periodic table?
Francium, with atomic number 87, does not have the highest atomic number. When it was discovered, in 1939, scientists already knew of five elements with higher atomic numbers: radium (88), actinium (89), thorium (90), protactinium (91) and uranium (92). By the end of 2015, the highest atomic number was 118 - for ununoctium.
What is an example of Atomic Number?
Atomic number= number of protons. Hydrogen atomic number=1
What is the atomic number of F plus the atomic number of Na?
The atomic number of fluorine is 9.The atomic number of sodium is 11.

What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?
What is the number of neutrons in an atomic number?
Subtract the atomic number from the atomic weight.
