The zero group elements have 8 electrons.
eg: Helium,Neon,Argon,Kromium.
They have thier outermost shell complete.So they are not reactive.
An oxygen atom has always 8 electrons (unless it's an ion where it has picked up 2 electrons and carries a -2 charge).In an O2 molecule there are 2*8 = 16 electrons and in an O3 molecule there are 3*8 = 24 electrons.
First you want to start with how many electrons there are in a neutral atom. In a neutral atom, the number of electrons equals the number of protons, which equals the atomic number, which is eight in this case. When becoming an ion and reacting with other elements in an ionic bond, oxygen will gain two electrons. So we just add two onto the number in a neutral atom for a total of ten.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
There are 8 valence electrons in the element Neon, as it is in group 18 of the periodic table.
There are 16 electrons in an oxygen molecule as each oxygen atom has 8 electrons.
Oxygen is a non metal element. There are 8 electrons in a single atom.
Oxygen is a non metal element. There are 8 electrons in a single atom.
The number of electrons corresponds to the "index" number of the element in the periodic table. The 8th element is Oxygen, which has 8 atoms when neutral. That didnt answer the question. ANSWER Neon has 8 electrons :)
The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8. For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
The number of valence electrons depends on the element and it could have 1 to 8 valence electrons.
Oxygen is a non metal element. There are 8 electrons in a single atom.

The nucleus of an atom contains protons and neutrons, not electrons. If an atom has 8 electrons, it is most likely the element oxygen, which has 8 protons in its nucleus.
Oxygen is a non metal element. There are 8 electrons in a single atom.
oxygen is an element. It is made of only atoms. So I guess 1, since 1 oxygen atom is 1 oxygen atoms. However, it has 6 protons and electrons.
