The nonmetals usually gain or share however many electrons they need to complete their outer shell. Metals tend to lose the electrons in their outer shell, so that one of the inner shells essentially becomes the outer shell.

How many electrons do alkalai metals have in their outer shell?
Alkali metals have 1 electron in their outer shell.
How many electrons are in the outer shell of sodium lithium and potassium?
Lithium and potassium are both alkali metals. Thus their outermost orbitals are filled up to s1. So, that shows us that they both have only one outer level electron each.
How do alkali metals atom achieve stability?
Alkali metals achieve stability by losing their outermost electron, which is in most cases the only electron in their outer energy level. By doing so, they achieve a full outer shell (octet) like the nearest noble gas, which increases their stability. This loss of an electron forms a positively charged ion that can easily bond with other elements to reach a stable electron configuration.
What do alkali metals have in common with electron shells?
Alkali metals have one electron in their outermost electron shell, making them highly reactive. The presence of this single electron makes them willing to donate it to achieve a stable electron configuration, which is typical of elements in group 1 of the periodic table.
Does Sodium have a full outer valence shell?
Sodium does not have a full outer valence shell. It has one electron in its outermost shell, which makes it very reactive and likely to lose that electron to achieve stability.
How many electrons do alkalai metals have in their outer shell?
Alkali metals have 1 electron in their outer shell.
Does lithium have a full outer shell?
no it only has 1 electron in the outer shell
What is the characterisitc of the outer electron shell of alkali metals?
The oute (valence) shell of the alkali metals contains just one electron
Why is sodium metal highly reactive when a sodium ion is not?
In the Group 1 and Group 2 elements, these metals want to loan out electrons to achieve what is called inert gas electron configuration, which is a full outer electron shell or valence shell. Because of their electron configurations as elemental metals, they are in a big hurry to do this (they are very reactive). In the ion, the metal has already loaned an electron (in the case of the Group 1 metals) or two electrons (in the case of the Group 2 metals). As an ion, the metal is "happy" because it has already reacted and loaned out the electron or electrons that will allow it to achieve inert gas electron configuration.
How many electrons are in the outer energy level of the atoms of alkali earth metals?
Alkali earth metals have 2 electrons in their outer energy level. This outer level is known as the valence shell, and having 2 electrons makes these metals highly reactive and likely to form ionic bonds to achieve a full outer shell of 8 electrons.
Explain why metals react with non-metals.?
Metals react with non-metals to achieve a stable electron configuration. Metals tend to lose electrons to achieve a full outer shell, while non-metals tend to gain electrons to fill their outer shell. This transfer of electrons between metals and non-metals results in the formation of ionic compounds.
How many electrons are in the outer shell of sodium lithium and potassium?
Lithium and potassium are both alkali metals. Thus their outermost orbitals are filled up to s1. So, that shows us that they both have only one outer level electron each.
Why does group 1 elements prefer to combine with group 17 elements?
Group 1 elements (alkali metals) prefer to combine with Group 17 elements (halogens) because alkali metals have one electron in their outer shell, which they can easily donate to achieve a stable electron configuration. Halogens, on the other hand, have seven electrons in their outer shell and can easily accept an electron to achieve a stable electron configuration. This electron transfer results in the formation of ionic compounds between alkali metals and halogens.
If an element is chemically active what is the state of its outer electron shell?
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.

Sodium has one electron in its outer shell According to the octet rule?
Sodium has one electron in its outer shell, so it tends to lose that electron to achieve a full outer shell. This makes sodium more stable as it follows the octet rule by having a complete outer electron shell with eight electrons.
