The group of elements that have a stable electron configuration are the noble gases.
Elements in group two become more stable as they all have complete electron shell.They do not have valence electrons and hence they are less reactive.Some of the elements of group 2 are Barium,Magnesium and Calcium
The atoms of Group 17 elements must gain one electron in order to become stable.
It is in Group 17 that you will find the most reactive elements. These elements all lack only one electron from having that "magic" electron configuration of the inert gases. That makes these elements very "hungry" to get that "last electron" so their electron structures become more stable.
i guess you mean that the group 1 elements usually lose a electron in order to become stable because the outermost of the group 1 elements have only one valence electron and it is easy to lose one than to gain seven.
Alkali Metals are group One elements and have one electron in their outer electron shell. In order to become stable they tend to lose an electron by reacting with something that needs an electron to become stable such as a group seven halogen. The Alkali Metal then become positive ions.This is because they only have on valance electron. This makes it easier to react with other elements and more often also.
all elements in group 8 are very stable as they have 8 electrons in their outermost electron shell, satisfying the octet rule. They are very stable and are called noble gas. they exist in a monoatomic gas.
Group 17 elements are non metals. Any element in group 17 are ready to obtain its stable electron configuration by sharing an electron with another non metal for a bond. Two examples are gaseous chlorine and iodine fluoride.
In the modern periodic table, these elements belong to group 17. These elements have s2 p5 electron configuration. Hence they need one more electron from an electron donor to fulfill its valence shell to obtain noble gas configuration.The elements in the group 7A has 7 electrons in their outermost energy level. They gain 1 electron to get the noble gas configuration. The elements in the group 7A are called halogens.
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
Atoms with full outer electron shells are more stable. The atoms (elements) with full outer electron shells are the noble (sometimes called inert) gases. These are the elements in Group 18 of the periodic table, and you know them as helium, neon, argon, krypton, exnon and radon.
the most stable element group is the noble gases group
The inert or noble gases have a stable full outer shell of electrons which is why they are so unreactive.
