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.
Nothing! If its outermost shell is filled with electrons, it will not have a need to go through an process to gain electrons( like the Noble Gases).
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.
O is the symbol for Oxygen, which is not a noble gas.No, Oxygen (O) is in group 6 and the noble gases (or inert gases) are in group 8.oxygen is not a noble gas because in order to become a noble gas it is necessary to have a completely filled outermost shell. as oxygen has only 6 electrons in its outermost shell it is not a noble gas because noble gases have 8 electrons which completely fill the outermost shell
Magnesium
Sulphur has 6 electrons in its outermost shell.
There are 2 electrons on the outermost shell of calcium.
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.
If it's outermost electron shell is filled.
If it's outermost electron shell is filled.
they become stable as they have completely filled outermost valence shell and if they have no electron in their outermost shell they become non reactive.
If it's outermost electron shell is filled.
Alkali metals have only 1 electron in their outermost (ultimate) shell. This means the atom needs energy to loose only one electron to have a completely filled outermost shell. Other atoms with 2 or 3 electrons would have needed more than twice or thrice the energy than these to loose electrons. Hence alkali metals are highly reactive compared to others. Like alkali metals, who need to LOOSE 1 electron to have a completely filled outermost shell, halogens need to GAIN 1 electron to have a completely filled outermost shell. With the same theory mentioned above, they are highly reactive.
no S is not a noble gas inorder to become a noble gas u need to have a completely filled outermost shell
The outer shell is completely filled.
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.

Noble gases have completely filled valence electrons. Helium has 2, other elements have 8
