What is the maximum number of valence electrons that an atom can have excluding hydrogen helium and beryllium?
The maximum number of valence electrons will vary from element to element ranging from 1 to 8.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
What is heliums number of valence electrons?
Helium has 2 valence electrons.
What is the number of valency electron in helium?
Helium has two valence electrons.
Do helium has the same number of electrons in the outer shell as in magnesium?
Yes, helium only has two electrons which makes up its valence electrons (also known as an outer shell) and magnesium also has two valence electrons.

The maximum number of valence electrons will vary from element to element ranging from 1 to 8.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
What is heliums number of valence electrons?
Helium has 2 valence electrons.
What is the number of valency electron in helium?
Helium has two valence electrons.
How many valence electrons are in an atom of helium?
helium has 2 electrons as its atomic number is 2
What is the maximum number of electrons that might be found in the valence shell?
The maximum number of electrons that might be found in the valence shell is eight.
Are valence electrons the number of protons?
Only for hydrogen and helium are these two numbers the same. All other elements have at least two non-valence electrons, and the total number of electrons must be equal to the number of protons. Therefore, in all elements except hydrogen and helium, the number of valence electrons is less than the number of protons.
Do helium has the same number of electrons in the outer shell as in magnesium?
Yes, helium only has two electrons which makes up its valence electrons (also known as an outer shell) and magnesium also has two valence electrons.
Do Aluminum has the greatest number of valence electrons?
Far from it. Aluminum has 3 valence electrons. The highest number is 8, which the noble gases other than helium have (helium has only 2). Metals can have 1, 2, or 3 valence electrons, so aluminum has the greatest number that an element can have if it is a metal. Once you get to 4 valence electrons (which the element carbon has) you are in the nonmetal range.
What do you notice about the number of electrons in each valence shell of noble gases?
All the noble gases have 8 electrons in their valence shell except helium which have 2 electrons in its valence shell.
In group 8 on the Periodic Table what element does not have 8 valence electrons?
Helium. It has 2 electrons in its single shell.
How many valance electron does krypton have?
Since krypton is a noble gas in the group number 18, it has 8 valence electrons. Eight is the maximum number of valence electrons.
