Elements with atomic numbers higher than 10 generally do not have 8 electrons in their outermost energy level. These elements tend to follow the octet rule, where they aim to have 8 electrons in their outer shell to achieve stability. Exceptions include elements such as transition metals that can have variable oxidation states.

How many valence electrons does group 8 have?
Group 8 elements, also known as the noble gases, have 8 valence electrons. This is the maximum number of electrons that can occupy the outer shell of an atom, giving them stability and low reactivity.
How many electrons are in the highest occupied energy level in Group 8A?
Group 8A elements have 8 valence electrons. This means that the highest occupied energy level in Group 8A elements will have 8 electrons, as the maximum number of electrons in an energy level is 8 based on the octet rule.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
In most elements the valence shell holds a maximum of how many electrons?
In most elements, the valence shell holds a maximum of 8 electrons. This is known as the octet rule, where atoms tend to gain, lose, or share electrons in order to achieve a full valence shell of 8 electrons, making them more stable.
Name the 8 valence electrons for argon?
The 8 valence electrons for argon are located in the 3s and 3p orbitals, with two electrons in the 3s orbital and six electrons in the 3p orbital.

Group 8A elements have 8 valence electrons. This means that the highest occupied energy level in Group 8A elements will have 8 electrons, as the maximum number of electrons in an energy level is 8 based on the octet rule.
Are elements with 8 outer electrons stable?
yes
What does it mean if an elements has 8 valence electrons?
it has a full octet
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
How many valance electrons are found in an atom what elements Neon?
there are 8 electrons in the valence shell of neon
In most elements the valence shell holds a maximum of how many electrons?

The 8 valence electrons for argon are located in the 3s and 3p orbitals, with two electrons in the 3s orbital and six electrons in the 3p orbital.
Elements that have 8 electron?
Oxygen has 8 electrons (2 in the inner shell, 6 in the outer).
How many valence electrons can an atom have?
An atom can have a maximum of 8 valence electrons in its outermost energy level, except for hydrogen and helium, which can only have a maximum of 2 valence electrons. The number of valence electrons determines an atom's chemical properties and reactivity. Elements in the same group on the periodic table have the same number of valence electrons.
How many valence electrons do most elements need to become stable?
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.
What does it mean when an elements has 8 valence electrons?
It means that there are 8 electrons in the outer most shell of the atom. Atoms with 8 valence electrons are generally stable.
