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

Which group in the periodic table would need only 1 electron to be stable?
The atoms of Group 17 elements must gain one electron in order to become stable.
What group of elements tends to form plus 1 charge?
The Alkaline metals (Group 1 metals). This is because they all have one valence electron and to become more stable by completing their outer shells, it is easier to lose 1 electron than it is to gain 7.
Which element in group VIII are very stable?
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.
Atoms of what elements will become most stable by gaining one electron?
Look here's the easy way. Look at the outer most valence shell. Is it filled? No? Will adding an electron fill it? If yes, then losing the outer most valence shell's electron will make the the atom a cation/positive charge.
How many electrons are required in the outer energy level for most elements to be stable?
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.
What group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
Which group in the periodic table would need only 1 electron to be stable?
The atoms of Group 17 elements must gain one electron in order to become stable.
Why are Alkali metals so reactive?
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.
What is the most reactive group of elements?
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.
What is outer shell electrons do group 1 elements?
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.
How do elements in group 1 of the periodic table become more stable?
They lose it
What group of elements tends to form plus 1 charge?
The Alkaline metals (Group 1 metals). This is because they all have one valence electron and to become more stable by completing their outer shells, it is easier to lose 1 electron than it is to gain 7.
How many electrons does group 7A need to become stable?
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.
Which element in group VIII are very stable?
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.
How many electrons would fluorine have to gain or lose too become stable?
Fluorine has 7 valence electrons. In order to become stable, Florine will share 1 electron with another atom to get 8 electron and become stable.
Atoms of what elements will become most stable by gaining one electron?
Look here's the easy way. Look at the outer most valence shell. Is it filled? No? Will adding an electron fill it? If yes, then losing the outer most valence shell's electron will make the the atom a cation/positive charge.
Which two elements fron group 17 are going to bond?
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.
