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.

∙ 15y agoMetallic atoms gain full outer shells by losing their outer electrons, becoming positively charged ions. Sodium (Na) has a valency of 1, and when it loses that electron, it becomes a 1+ ion. Na+ positive ions will then form ionic bonds with negative ions to balance their charges.

What happens to the electrons in the outer shell when the alkali metals react with other elements?
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
How many electrons do alkalai metals have in their outer shell?
1 electron.
What is the difference between alkali metals and alkali earth metals?
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
What do alkali metals have in common with electron shells?
They all have 0NE electron in their outer shell: called s-electron. That's why they belong to group 1
What is characteristic about the outer electron shells of alkali metals?
since all the alkali metals have one electron in there outer most shell so there valency is always one & they are the most electropositive elements in the periodic table.they loose one electron from there outermost shell to form one positive charged cations.
What happens to the electrons in the outer shell when the alkali metals react with other elements?
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most 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
How many electrons do alkalai metals have in their outer shell?
1 electron.
What is the difference between alkali metals and alkali earth metals?
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
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.
Atoms in what group has one less electron than a full orbit?
Atoms in Group 1, also known as alkali metals, typically have one less electron than a full outer orbit. These elements have one electron in their outermost shell, making them highly reactive and likely to lose that electron to achieve a more stable, full outer shell configuration.
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.
How are francium and lithium related if francium has 87 electrons and lithium has three?
Both francium and lithium have 1 electron in their outer electron shell and have a partially filled s-orbital. Both metals easily lose this outer shell electron.
What do alkali metals have in common with electron shells?
They all have 0NE electron in their outer shell: called s-electron. That's why they belong to group 1

Why are the alkaline-earth metals less reactive than the alkali metals?
Alkaline-earth metal have two electrons in there outer shell, so only need to lose one to form a stable electron arrangement. Alkali metals have one electron in there outer shell - so they need only lose one to form a stable electron arrangement
Why is chlorine diatomic?
A lone chlorine atom has 7 outer shell electrons, 1 electron short of a full outer shell of 8 electrons, which is stable. In order to achieve this full outer shell two chlorine atoms share a pair of electrons, with each atom contributing 1 electron to the pair. By sharing electrons in this manner the chlorine atoms achieve a full outer shell.
