How many electrons do the elements of the most stable group have in their outer shells?
Elements in the most stable group of the periodic table, also known as the noble gases, have full outer shells. This means they have 2 electrons in the case of helium, and 8 electrons for all other noble gases.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
What is the groups number for elements that have a stable number of electrons in their outer energy level?
Group 8
How many valence electrons will make an element happy or stable?
Most elements are stable with a full outer shell of electrons, typically with 8 electrons known as the octet rule. However, elements in the first shell can be stable with 2 electrons. This full outer shell results in a stable configuration similar to the noble gases, making the element happy or stable.
How do element become stable?
The elements can only be stable when it complete is octate in its outer most orbit has 8 electrons in its outer most orbit by gaining or losing energy
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.
Is the outer shell of argon full?
Yes it is . The outer argon is full becoz it has 18 electrons
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
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.
How many electrons will a non metal generally have in its outer shell?
non-metals have between 3 and 8 electrons in the outer shell. You can tell how many they have by looking at which period they're in on the periodic table, period 13 elements have 3, period 15 elements have 5 ect.
What is the most stable outer orbital arrangement of electrons after a chemical reaction?
The most stable outer orbital arrangement of electrons after a chemical reaction is typically achieved when the atom has a full outer shell of electrons, usually eight electrons (except for hydrogen and helium, which have a full outer shell with two electrons). This configuration is known as the octet rule and is associated with greater stability due to a lower energy state.
Which atom does not need 8 electrons in it outer energy level to be stable?
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
