How many electrons does oxygen need to gain to get a full outer shell?
Boyyyy
Oxygen already has 6 valence electrons, so it needs two more to complete its octet.

Why is chlorine diatomic?
A lone chlorine atom has 7 outer shell electrons, 1 electron short of a full outer shell of 8 electrons, which is stable. In order to achieve this full outer shell two chlorine atoms share a pair of electrons, with each atom contributing 1 electron to the pair. By sharing electrons in this manner the chlorine atoms achieve a full outer shell.
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.
Does helium have a complete outer shell?
Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell. Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.
Calcium Sulfide formula?
CaS Because Calcium has 2 electrons in its outer shell- so it needs to get rid of those (Ca2+) Sulfur has 6 electrons in its outer shell- so it needs 2 more to have a full outer shell (S2-)
If an atom has a stable number of electrons how can you tell?
It's outer valence shell is full.
Why does does oxygen and hydrogen react together?
because they both want to gain full outer shell. They don't have completed outer shells. Hydrogen has one electron in it's outer shell so it wants to ger rid of that by giving it to oxygen. (oxygen itself needs two electrons to get full outer shell which is 8 electrons, so two hydrogens are needed to complete one oxygen atom) and then water is formed.
How many valence electrons does oxygen need to have a full outer valence shell?
Oxygen is in group 16 so it has 6 valence electrons. In order to have a full outer shell, and satisfy the octet rule, it needs 2 more valence electrons to have a full outer shell.
Would Oxygen gain or lose an electron when forming an ion?
Oxygen will gain two electrons to achieve a full outer shell.
Why does oxygen form with an ion with -2 charge?
A lone, neutral oxygen atom has 6 electrons in its outer shell, but this is not very stable, so oxygen will tend to gain 2 more electrons in order to get a full, stable shell of 8 electrons.
Argon is a stable gas with a very high ionization energy Which statement explains why?
It has a full outer shell of electrons
Why is O the element symbol for oxygen?
A lone oxygen atom has 6 outer shell or valence electrons but like other atoms, is most stable with a full outer shell of 8 electrons. In order to get this full outer shell, the oxygen atoms shares electrons with another atom, this is called a covalent bond. In the O2 molecule there are two oxygen atoms bonded together. Each atom contributes 2 electrons to be shared between both atoms, allowing each atom to achieve a full outer shell.
How many electrons does an oxygen atom want to have in its outer sell?
"Want" is a word you should try to avoid when talking about atoms. Oxygen reacts to get a full outer shell of 8.
What evidence do you have that water is a covalent bond?
Because when hydrogen atoms combine with the oxygen atom, they do so by sharing their outer shell electrons to gain a full outer shell. Hope this helps
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer valence shell.
What would be the charge of a beryllium atom that has a full outer shell?
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2
Why would two oxygen atoms want to form a double covalent bond?
A lone oxygen atom has 6 electrons in its outer shell which is not very stable, whereas as full octet (8 outer shell electrons) is stable. In order to achieve this two oxygen atoms will share 4 electrons, each contributing 2 electrons. Since these electrons exist within the orbitals of both atoms, to oxygen atoms essentially achieve a full octet.
An element is inactive if?
It has a full outer shell of electrons.
