No, Hydrogen, Lithium and Beryllium tend to complete 2 electrons in outermost shell and most of the Transition metals tend to complete 18 electrons and other 8 electrons.
only in the noble gases family.
They all want 8 electrons!
8 electrons
When non-metals bond together, they share electrons. This is called a covalent bond. By sharing pairs of electrons, two or more different atoms can claim they have 8 electrons in their outer energy level, which gives them noble gas configuration, which they all want. If they share one pair of electrons, it's a single covalent bond. Two pairs is a double, and three pairs is a triple. Whatever it takes to get to 8.
This value could vary from element to element and atoms could have 1 to 8 valence electrons.
Bonds are formed between two atoms because that results in a more stable state for the atoms. This is a result of electron configuration where most atoms want to have 8 electrons in their outer-most orbital (there are exceptions to this rule, however).
They all want 8 electrons!
A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
Atoms combine in order to become stable, which for most atoms means having 8 valence electrons.
more electrons because all atoms want to be like noble gases and will either give or take electrons to obtain 8 electrons so atoms with either 1 or 2 electrons would wither give off 1 or 2 electrons depending on how many then had
Since a carbon atom has 4 electrons in its outer shell, it does not have the stable arrangement of 8, which it can gain by sharing electrons with other atoms.
When an atom gains or loses electrons, it gains a negative or positive charge respectively. Atoms generally try to gain enough electrons to fill their outer, valence electron shell. For the first shell the number of electrons is 2 and for all others, atoms usually want 8 electrons.
All oxygen atoms contain 8 protons in their nuclei. All neutral oxygen atoms have 8 electrons. There are three isotopes of oxygen, containing 8,9, or 10 neutrons in their nuclei.

A completely filled shell of electrons has 8 electrons.
8 electrons
Electrons are arranged in electron clouds around the nucleus. The reactivity is determined by the number of valence electrons, or electrons in the outermost energy levels. All atoms (except for hydrogen who wants 2 electrons and boron who wants 6) want 8 valence electrons, or a full outer energy level. This makes them stable (like the noble gases). If an atom has 1 valence electron it will desperately want to lose that electron while an atom with 7 electrons will want to gain one electron. All atoms have the goal of 8 valence electrons. Also, the 1st energy level only has 2 electrons. After that there is 8 electrons (approximately, because you can never truly determine where an electron is inside of an atom at any given time).
it has 4 protons and 15 electrons!!!Ans 2.Oxygen has 8 protons.p.s. like all atoms, it has the same number of electrons as protons : 8.
