These are the Noble gases which are generally inert. (Except for Helium, which has two electrons, but which is still considered a Noble Gas.)
The zero group elements have 8 electrons.
eg: Helium,Neon,Argon,Kromium.
They have thier outermost shell complete.So they are not reactive.
All the noble gases have eight electrons in their outermost shell which makes their valence shell complete.
Oxygen
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.
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.
A molecule of methane contains 8 valence electrons: 4 from the carbon atom and 1 from each of the 4 hydrogen atoms.
A chloride anion contains eight outer shell electrons, one more than the seven outer shell electrons found in a chlorine atom.
8 electrons.
Oxygen is a non metal element. There are 8 electrons in a single 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.
Oxygen is a non metal element. There are 8 electrons in a single atom.
Copper is a non metal element. There are 29 electrons in a single atom.
Oxygen is a chemical metal element. There are 8 electrons in a single atom.
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.
The maximum number of valence electrons will vary from element to element ranging from 1 to 8.
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.

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.
