How many more valence electrons does oxygen need to have a full outer?

Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.

How many more valance electrons does oxygen need to have a full outer valence shell?

None. Neon is a noble gas, a category of elements that exist in nature as inert gasses. In special situations, neon can be made to react with other elements, but in ordinary conditions, neon is inert, which just means non-reactive. It's outer orbit is full--it doesn't want to give up the electrons it has, or to take any more.


What is the valence of Xenon?

Xenon has a valence of 0, as it is a noble gas and has a full outer shell of electrons.


If an atom has a stable number of electrons how can you tell?

If an atom has a stable number of electrons, it will have a full outer electron shell (valence shell). This full outer shell will typically have 2, 8, 18, or 32 electrons, depending on the period the atom is in. Atoms with full valence shells are considered stable because they are less likely to undergo chemical reactions to gain or lose electrons.

How many valence electrons are needed to achieve a full outer shell?

It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!


How many number of electrons to fill the outer shell of carbon?

Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.


How many valence electronss are there in Boron?

There are three valance electrons. These are the electrons in the outer shell if it is not full.


How many electrons are in the outer shell of Ar?

Argon has eight valence (outer) shell electrons. It is a Noble Gas so its valence shell is full (Octet Rule).
