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.

∙ 15y agoThe element with the largest atomic number will have the largest number of electrons. Roentgenium (111) is the largest named element, but I think some of the heavier elements have been briefly formed (but are severely lacking in neutrons to stick around for very long).

Which element holds its electrons most tightly?
Hydrogenium. It has one electron, so that one is in his own direction. in the other elements they pair up. one electrone,
Is fluorine a substance?
Yes, Fluorine is an element. It comes in the form of a gas composed of F2 molecules. It is the most electronegative of all the elements and is extremely reactive.
What halogen is most likely to react?
The reactivity of halogens decreases down the group, which means Fluorine is the most reactive halogens as it is the most electronegative elements among the halogens, and also the Periodic Table.
Which is the most electronegative element lithium or oxygen?
Across a period, electronegativity increases. Hence oxygen is more electronegative than lithium. However fluorine is the most electronegative element on the periodic table.
Which element is the most electronegative element?
The most electronegative element fluorine.
What of these elements is the most electronegative?
Fluorine
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.
Electrons in oxygen?
yes oxygen is electronegative,it is one of the most electronegative elements in the periodic table,its electronegativity is 3.44
What elements is the most electronegative Argon Chlorine Phosphorus or Sulfur?
Chlorine.
Where are the elements with the most electronegativity on the periodic table?
Fluorine (F) is the most electronegative element in the periodic table. For more info: see related link
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.
Which elements is most electronegative phosphorus carbon chlorine boron iodine?
Chlorine
In which section of the periodic table are the most electronegative elements found?
Lower left
What element is most active?
The most electronegative of all elements is fluorine, at 3.98 on the Pauling scale.
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)
Which pair of elements will most readily form a compound?
elements that may form a compound, are elements that are different from each other, and they also have to be more than 1 element to combine, and create.
