What group on the periodic table has the most stable amount of valence electrons?

That would be the Nobel gasses, 8A, because they have an octet of 8 electrons fully filling their valance shells so that they naturally do not react with other elements is either ionic or covalent bonding.

When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
What are Helium and neon classified as on the Periodic table?
these gases are the noble gases or inert gases. They are non reactive and have stable valence electrons
How many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
Where is the most Stable outer orbital arrangement of electrons?
The noble gases - group 18 on most newer periodic tables - are the most stable. They have a completely filled valence shell of electrons.
Have two valence electrons and get to a stable electron configuration by using two electrons?
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
How many valence electrons do stable atoms have?
A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
How many Valence electrons in a stable octet?
8 valence electrons
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
What rules are used to assign oxidation number?
First, determine which family it is in on the periodic table. The group number equals the number of valence electrons that it has. It needs to end up with eight valence electrons to have a full octet. So if it has seven valence electrons, it will gain one electron to be stable. On the other end of the table, it will lose electrons to be stable.
What are Helium and neon classified as on the Periodic table?
these gases are the noble gases or inert gases. They are non reactive and have stable valence electrons
How can you find the valence electrons for an atom?
To find the valence electrons, you look at the periodic table. The first column (Li on down) have one. You continue this pattern until you reach the Nobel Gasses, which are very stable with 0 valence electrons. Remember not to count the valence electrons using the "d" sublevel, or the middle "carved-out" part of the table.
How does boron's position in the periodic table hint that it is stable when bonded to only three atoms?
Boron tends to form molecules in which it is surrounded by only six valence electrons. Boron only has three valence electrons, and fluorine already has seven of the eight electrons it needs to fulfill its octet to be stable. Hope it helps!
How many valence electrons will result in chemical stability for an atom?
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
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.
When is a periodic orbit stable?
when the shells have complete electrons they are stable
Valence electrons found where?
Valence electron are found in the outer shell of an atom. Depending on the number of valence electrons, the atom is more or less stable: fewer => less stable and more => more stable (inert). Stable = less likely to react with other atoms.
