Basically, the more electrons that are present in an atom, the more elctron shells it will have. Look at a periodic table and you'll see Astatine has a proton number of 85 (85 protons), as the number of electrons and protons is equal, we can therefore deduce that it has 85 electrons and is the largest halogen atom. Therefore astatine MUST have the most electron shells as it has more electrons to fill them. Basically, the more electrons that are present in an atom, the more elctron shells it will have.

What else can I help you with?
Which element is the most electronegative element?
The most electronegative element fluorine.
Physical characteristics of fluorine?
Fluorine is a pale yellow-green gas at room temperature with a pungent odor. It is the most electronegative element, highly reactive and a strong oxidizing agent. Fluorine is the most chemically reactive of all the elements.
Which element holds its electrons most tightly?
Fluorine holds its electrons most tightly among the elements. This is because fluorine has the highest electronegativity value on the periodic table. Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
Which is the most electronegative element lithium or oxygen?
Oxygen is more electronegative than lithium. Electronegativity refers to an element's ability to attract electrons in a chemical bond, and oxygen has a higher electronegativity value compared to lithium on the periodic table.
Is hydrogen more electronegative than chlorine?
No, on the Arbitrary Pauling Scale hydrogen's relative electronegativity is less than that of chlorine, indicating that hydrogen attracts electrons in a bond more strongly. In hydrogen chloride (hydrochloric acid as an acid) the two shared electrons would be pulled towards hydrogen in a polar covalent bond. F, Cl, N, and O are the four most electronegative elements. Metals are least electronegative and nonmetals are the most.
What of these elements is the most electronegative?
Fluorine is the most electronegative element.
What elements has the highest electronegative F O or N?
Fluorine. It is the most electronegative element.
What part of the periodic table is the most reactive and least reactive?
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Where are most electronegative elements located on periodic table?
Electronegativity is a characteristic property shared by ALL elements. Non-metals have the greatest (strongest force of electron attraction), and metals have the least (weak force of electron attraction)
What is meant by electronegative?
The ability of an atom to attract electrons. The most electronegative elements are in the upper right hand corner of the Periodic Table, most notably fluorine.
What element is most active?
The most electronegative of all elements is fluorine, at 3.98 on the Pauling scale.
In which section of the periodic table are the most electronegative elements found?
The most electronegative elements are found in the top right corner of the periodic table, in the halogen group (Group 17). These elements include fluorine, chlorine, bromine, iodine, and astatine.
Is fluorine electropositive?
No, no, no... Fluorine is the most electronegative of all
Which elements is most electronegative phosphorus carbon chlorine boron iodine?
Iodine is the most electronegative element among phosphorus, carbon, chlorine, boron, and iodine.
What is most chemically active Element?
The most electronegative of all elements is fluorine, at 3.98 on the Pauling scale.
What is the most chemically active element?
The most electronegative of all elements is fluorine, at 3.98 on the Pauling scale.
Which one is the most electronegative element in the periodic table?
Chlorine is most electronegative element. It is halogen.It is placed in group-17.The most electronegative element in the periodic table is Fluorine. The electronegativity of elements increase from left to right of a period. And decreases own a group.
