These are the Noble gases which are generally inert. (Except for Helium, which has two electrons, but which is still considered a Noble Gas.)

eg: Helium,Neon,Argon,Kromium.
They have thier outermost shell complete.So they are not reactive.

How many eletrons are in oxygen?
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.
How many electrons does an ion of oxygen have?
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.
How many valence electrons does methane diazonium ion have?
A molecule of methane contains 8 valence electrons: 4 from the carbon atom and 1 from each of the 4 hydrogen atoms.
What number of electrons in the outer outer shell of Cl?
A chloride anion contains eight outer shell electrons, one more than the seven outer shell electrons found in a chlorine atom.
What is the maximum number of electrons an element with two energy levels can have?
8 electrons.
How many electrons are in oxygen?
Oxygen is a non metal element. There are 8 electrons in a single atom.
How many electrons can an atom hold in its outermost level?
The number of valence electrons depends on the element and it could have 1 to 8 valence electrons.
How many electrons in the element oxygen?
Oxygen is a non metal element. There are 8 electrons in a single atom.
How many electrons does element oxygen have?
Oxygen is a non metal element. There are 8 electrons in a single atom.
How many outer shell electrons does copper have?
Copper is a non metal element. There are 29 electrons in a single atom.
How many electrons arranged in an oxygen atom?
Oxygen is a chemical metal element. There are 8 electrons in a single atom.
Are Atoms of one element are different from atoms of other elements?
Yes. Atoms are unique to whichever element they compose. They have different amounts of electrons, protons and (neutrons). For Example: Hydrogen Atom: 1 electron, 1 proton. Oxygen Atom: 8 electrons, 8 protons, 8 neutrons.
What is the maximum number of valence electrons that an atom can have excluding hydrogen helium and beryllium?
The maximum number of valence electrons will vary from element to element ranging from 1 to 8.
How many electrons does this element have O?
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.
How many electrons does o element have?
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.
Are the elements oxygen and the element hydrogen made from the same of atom?
No. A Hydrogen atom has 1 proton and 1 electron with the electron arrangement 1. An Oxygen atom has 8 protons, 8 neutrons and 8 electrons with the elecron arrangement 2. 6.
How many electrons does this oxygen?
Oxygen is a non metal element. There are 8 electrons in a single atom.
