Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
4 electrons in its outermost energy level to be filled.
Carbon needs eight electrons to have it's outermost energy level filled.
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because it wants to acquire a filled outermost energy level.
An oxygen atom has eight electrons. The first electron shell can contain two electrons so that shell is filled leaving six electrons left. Since the second electron shell can contain up to eight electrons, the remaining six electrons go into the second shell. Since the second shell is the outermost shell, there are six electron's in the outer energy level.
Answer When the outermost shell(valence shell) is filled the atom is to be most stable. First Shell: holds up to 2 electrons Second Shell: holds up to 8 electrons Third Shell: holds up to 18 electrons Fourth Shell: holds up to 32 electrons
An electrically charged atom or group of atoms with an unpaired electron in its outermost shell is called a free radical. If the outermost shell of an atom is half-filled with electrons, that atom is most likely to share electrons.
They are most likely to lose or gain atoms. For example if u have two atoms with uneven electrons then one of the two will take the other one's to balance each other out.
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Helium only needs 2 valence electrons to have a filled outermost energy level.
8 electrons
Completely filled octet.
Outer energy level electrons, or valence electron.
Completely filled octet.
0 It already is full
To become stable. When the outermost energy field is filled to maximum electrons, the atom is stable.
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because it wants to acquire a filled outermost energy level.
It is stable when filled with electrons.
helium has completely filled valence orbitals and hence is stable
