The noble gasses have a full outer shell of 8 electrons, called on octet (except for helium, which has 2). This is a stable configuration and other elements undergo chemical reactions to approximate it. By contrast the alkali metals have only one outer shell electron which they readily lose in order to go down to the full outer shell below it. The electrons in the lower shells also shield the outer electron from the nucleus, so there is less attraction and the electron is only held loosely. By contrast a noble gas in the same row of a given alkali metal has the same number of electron shells, but the positive charge on its nucleus, so there is a greater force of attraction holding the electrons in place.
What else can I help you with?
How are alkali metals to noble gases?
Alkali metals are highly reactive and tend to form ionic bonds with other elements, while noble gases are nonreactive and exist as stable, monatomic gases in nature. Alkali metals readily donate an electron to achieve a stable electron configuration, while noble gases already have a full valence shell, making them highly stable and unreactive.
What groups are stable Alkali metals or alkanie metals or earth metals or halogens or noble gases?
Noble gases are the most stable group of elements due to having a full valence shell of electrons, making them generally unreactive. Alkali metals are highly reactive due to their tendency to lose one electron to achieve a stable electron configuration. Alkaline earth metals are less reactive than alkali metals, but more reactive than noble gases. Halogens are highly reactive nonmetals due to their tendency to gain one electron to achieve a full valence shell.
What are 2 simmilarities between noble gases and alkali metals?
If alkali metals loses one electron, they achieve the electronic configuration of the nearest noble gases.
In the same period what have large atomic radii alkali metals or noble gases?
Noble gases have larger atomic radii than alkali metals in the same period.
What would alkali metal atoms need in order to end up with the same stable electron arrangements as the noble gas?
Alkali metal atoms need to lose one electron to achieve the stable electron arrangement of the nearest noble gas. This is because the noble gases have a full valence shell, which is more stable. By losing an electron, the alkali metal atoms achieve a full valence shell and become more stable.

Are the most stable elements you the periodic table are found in the family of alkali metals?
No, the most stable elements on the periodic table are typically found in the noble gas family. Alkali metals, such as lithium and sodium, are relatively reactive compared to noble gases like helium and neon, which have full valence shells and are therefore more stable.
What are 2 simmilarities between noble gases and alkali metals?
If alkali metals loses one electron, they achieve the electronic configuration of the nearest noble gases.
How many electrons away from a noble gas are the alkali metals?
Alkali metals have one electron more than the noble gases.
In the same period what have large atomic radii alkali metals or noble gases?
Noble gases have larger atomic radii than alkali metals in the same period.
What are the families in periodic table?
alkali metals, alkali earth, transition metals, non metals, halogens, noble gases
What is the correct list of elemental families in order going from left to right?
Alkali metals, transition metals, halogens or Transition metals, halogens, noble gases or Alkali earth metals, halogens, noble gases
What are the different types of family of elements?
Examples: alkali metals, alkali earth metals, noble gases, platinum metals, halogens, etc.
Why do alkali metals have lower ionization energies than the alkali earth metals?
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.
What are group 8A elements called?
I - Alkali Metals II - Earth Alkali Metals III - Boron Group IV - Carbon Group V - Nitrogen Group VI - Chalcogenes VII - Halogenes VIII - Noble Gases
What are the 5families in the periodic table?
alkali F., alkali earth metals, coinage, halogens and noble gases
