What else can I help you with?
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 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 is the maximum number of valence electrons that an atom can have excluding hydrogen helium and beryllium?
The maximum number of valence electrons that an atom can have is 7, as seen in elements such as fluorine, chlorine, and bromine. These elements are in group 7A of the periodic table, also known as the halogens.
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.
What is the number of valency electron in helium?
Helium has two valence electrons.

What is the number of valency electron in helium?
Helium has two valence electrons.
What is heliums number of valence electrons?
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
How many valence electrons are in an atom of helium?
helium has 2 electrons as its atomic number is 2
Does helium have the same amount of valence electrons as the others in its group?
No it does not, there are shells and orbitals that determines how reactive an atom is. Helium has 2 valence electrons, which fill up its entire shell, so it is like a noble gas. the other noble gasses have 8 valence electrons, which fill up their entire shell.
All noble gases except helium have this?
Helium has 2 valence electrons. All other noble gases have 8 valence electrons.
What is the maximum number of electrons that might be found in the valence shell?
The maximum number of electrons that can be found in the valence shell is 8. This is known as the octet rule, which states that atoms tend to gain, lose, or share electrons to achieve a full valence shell of 8 electrons.
Which group contains the least number of valence electrons?
Noble gases contain the least number of valence electrons, with a full outer shell of eight electrons (except for helium, which has two 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.
