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.
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.
An electrically neutral oxygen atom has eight electrons, one for each proton in its nucleus. Two electrons are in the inner shell and six are in the outer shell.
First shell contains atmost two electrons. The formula is 2n. where n is the no. of shell u want to calculate its capacity of no of electrons..thanku

Oxygen has 2 electrons in its first energy level.
Oxygen has 8 electrons (assuming its charge is 0), and in the first shell ("closest" to the nucleus) there are 2 electrons. :)
In the first shell of oxygen, there are 2 electrons, and in the second shell, there are 6 electrons. Oxygen has 8 electrons in total, with 2 of them in the first shell and the remaining 6 in the second shell.
69.
In the very first shell it has 2 and then it has 6 (in the second shell). =)
The innermost shell of every atom except hydrogen consists of 2 electrons.
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.
Oxygen has 8 electrons in total. The distribution of these electrons in shells KLMN is as follows: K shell has 2 electrons, L shell has 6 electrons, M shell has 0 electrons, and N shell has 0 electrons.
The electron configuration of an oxygen atom is (2, 6). Meaning it has 2 electrons in its first shell and 6 in its second.The energy levels of atoms are limited to how many electrons they can hold.The first energy level can only hold a maximum of 2 electrons the second has a maximum of 8 and the third has a maximum of 18 etc.Hope this Helps!

there are two electrons the first shell hold
it has 6 electrons in the outer most shell
Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
