Which metals forms ions with a noble gas electron configuration?
Alkali metals and alkaline earth metals will form ions (by losing 1 and 2 electrons respectively) with noble gas electron configuration.
Why are alkali metals more reactive than other metals?
Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.
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.
What are the similarities between the noble gases and alkali metals?
There are no similarities. Noble gases (group 18 elements) have completely filled orbitals with stable electron configuration and are generally unreactive. Alkali metals (group 1 elements) have one valence electron. They are reactive. When these lose one electron, they form ions which has the electronic configuration of the nearest noble gas.
Why is hydrogen (H) placed with elements in Group 1A?
Properties of Hydrogen. Hydrogen is a nonmetal and is placed above group in the Periodic Table because it has ns1 electron configuration like the alkali metals.
Why hydrogen is placed above alkali metals and not above non metals in modern periodic table?
The electron configuration of hydrogen is similar with that of alkali metals.

Is hydrogen in the alkaili metals metals?
No. Hydrogen is a nonmetal. It is only put in the alkali metal column because it has a similar electron configuration.
How many valence electron does alkali metals have?
Alkali metals have one valence electron.
How do the valence electron configurations of the alkali metals compare with others?
The valance electron configuration is the same in each at ns1 where n = the period number.
What kind of atom tends to loose one electron?
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
What important characteristics do the alkali metals and earth metals have in common?
They all have at least one electron.
Does hydrogen behave like an alkali metal?
Yes, chemical similarities exist between hydrogen and alkali metals; also the electron configuration has a parallel.
What gas seem to be out of place?
Hydrogen. It is placed with the alkali metals in group 1 because of its electron configuration, but it is a nonmetal.
