How many electrons can an atom hold in its outermost level?

The number of valence electrons depends on the element and it could have 1 to 8 valence electrons.


What element has 118 and 8 valence electrons?

The element with atomic number 118 and 8 valence electrons is oganesson (Og). Oganesson belongs to the noble gas group and has a complete outer shell of valence electrons, making it stable and unreactive.


In group 8 on the Periodic Table what element does not have 8 valence electrons?

Iron (Fe) is in group 8 on the Periodic Table and it does not have 8 valence electrons. Iron has 2 valence electrons in its 4s orbital and 6 valence electrons in its 3d orbital, making a total of 8 valence electrons.


What is the maximum number of valance electrons an element can have?

The maximum number of valence electrons an element can have is 8. This is because the outermost energy level, or valence shell, of an atom can hold a maximum of 8 electrons. Exceptions to this rule can occur for elements that can have more than 8 electrons in their valence shell through the process of expanded octet.


Electrons that are held most loosely in an atom are called what?

The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.


What element is most reactive an en element with 7 valence electrons or an element with 8 valence electrons?

the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
