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.
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?
Alkali metals have 1 electron in their outer shell.
Why do noble gases not normally form compounds?
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.
Do noble gases have full outer shell of electrons?
Yes, noble gases have a full outer shell of electrons, which makes them highly stable and unreactive with other elements. This full outer shell configuration is why they are commonly referred to as inert gases.
Do noble gases have a maximum number of electrons in their outer energy level?
Yes they do, because, for example, neon has 2 electrons in its inner shell and 8 on its outer shell; these shells are both full. Helium, the lightest of the noble gases, has only 2 electrons, but that completes it only shell. All the other noble gases have 8 electrons in their outer shell, which is a stable arrangement.
How many electrons are in the outer electron shell in Alkali metas?
1 valence electron
Do all noble gases have the same number of electrons in their outer shell?
Yes they all have 8 electrons in the outer shell, with the exception of Helium which has only 2.
How many electrons are in the alkali metals shell?
There is 1 electron in the outer shell of a group one alkali metal. Just the same as there would be two electrons in the outer shell of a group 2 element.
How many electrons does Ar have in its outer shell?
Argon (Ar) has 8 electrons in its outer shell. This is because argon belongs in group 18 of the periodic table, known as the noble gases, which have a full outer shell of 8 electrons.
How many electrons does neon have in its outer shell?
Eight. Neon is one of the Inert (also know as the Noble) Gases. The Inert Gases are largely unreactive, due to their filled outer shell.
How many electrons does noble gases have in the outer shell?
8 electrons (except for helium which has 2)
