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.
How many electrons does nitrogen need to fill its outer shell?
Nitrogen needs 3 more electrons to fill its outer shell. It has 5 electrons in its outer shell, and it typically needs a total of 8 electrons to achieve a full outer shell (octet rule).
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.
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.
If an atom has fewer than 4 electrons in its outer shell does it looses electrons gain electrons or both?
The atom wants to have eight or full electrons in its outer valence ring... so if it has four electrons in its outer shell it has the choice of loosing four electrons or finding four electrons somewhere else (whichever is the easiest for it to bond with).
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 electrons does an atom of oxygen need to complete its outer shell?
An atom of oxygen needs 2 electrons to complete its outer shell, which can hold a total of 8 electrons. Oxygen has 6 electrons in its outer shell, so it will gain 2 electrons through bonding to achieve a full valence shell.
How many electrons does the oxygen atom need to became stable?
An oxygen atom needs 2 electrons to become stable because it has 6 electrons in its outer shell and it needs a total of 8 electrons to have a full valence shell. By gaining 2 electrons, oxygen can achieve a full outer shell and become stable.
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.
How many electrons can oxygen hold before it is full?
Oxygen can hold a maximum of 8 electrons before its outer shell is full. This allows it to achieve a full valence shell and become more stable.
Does calcium have a full outer shell?
Calcium has a full 4s sublevel, but does not have a full "outer shell", per se, because it is not a noble gas.
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 electrons does a neutral atom of oxygen usually have in it's outer orbit?
Oxygen has 6 valence electrons. These are in the outer orbit.
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.
How many electrons are in the outermost energy level of a oxygen atom as it shares electrons with hydrogen atoms as a part of a water molecule?
There are 6 electrons in the outermost energy level of an oxygen atom. In a water molecule, oxygen shares electrons with two hydrogen atoms to form covalent bonds, achieving a full outer shell with 8 electrons (octet rule). Oxygen shares one electron with each hydrogen atom to complete its outer shell.
Which element has 6 electrons in the outer shell?
2 because if it was 8 it would be a full shell. 2 because if it was 8 it would be a full shell. 2 because if it was 8 it would have a full shell....
Would Oxygen gain or lose an electron when forming an ion?
Oxygen will gain two electrons to achieve a full outer shell.
