How many electrons are in the outer shell of O?
Oxygen has 2 valence electrons.
How many electrons are in the outer shell of 0 atom?
Oxygen: 6 electrons
How many shell in oxygen atom?
Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
Why is the valency of oxygen 2 instead of 6?
The valency of an element indicates the way it will react in a chemical reaction. For example, oxygen has six outer electrons and only needs eight electrons to have a complete outer shell. It can either lose six electrons or gain two electrons. It is easier for an oxygen atom to gain two more electrons and therefore its valency is 2.
Why is there only one oxygen ion in magnesium oxide?
there are two electrons in magnesiums outer shell, and 6 in oxygens. In magnesium oxide the electrons from Mg are donated in order to give both elements complete outer shells
How many electons does an oxygen atom have in its outer shell?
An oxygen atom has six (6) electrons in its outer shell.
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 are in the outer shell of O?
Oxygen has 2 valence electrons.
How many electrons are in the outer shell of 0 atom?
Oxygen: 6 electrons
How many electrons are there in the outer shell of an oxygen atom?
8
How many electrons are shared between carbon and oxygen to complete the outer electron shell of all three atoms?
enoughh :L
How many electrons go in the first shell of oxygen?
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
How many electrons nitrogen has in its outer energy levels?
Nitrogen has atomic number = 7. The outer shell has 5 electrons, it requires 3 more electrons to complete the outer energy shell.
What element ha 6 electrons in the outer shell and 8 total?
It is Oxygen. Because Oxygen has the atomic no. - 8. Which means that 2 electrons can accommodate in the inner shell and the rest of the electrons (6 electrons) are in the out shell.
How many shell in oxygen atom?
Two. An inner shell contains 2 electrons; and an outer shell contains 2 electrons on its near side and 4 more electrons on its outer side. Total of 8 electrons.
WHY does it make sense that oxygen achieved full shell by gaining electron?
It doesn't. Oxygen must gain (or borrow) two electrons to complete its outer shell since it has only 6 electrons in its valence shell.Oxygen is atomic #8 in the periodic table, meaning it has 8 electrons. The first shell of an element needs only 2 electrons to be stable and relatively unreactive. Shells (energy levels) beyond the first need 8 electrons to be stable, but oxygen has only 6 left because 2 were used in the first shell. Therefore, oxygen needs 2 more to complete its outer (valence) shell.
How many electrons can an oxygen atom add to its outer shell?
2
