they all have a differnet number of electrons, but all have a charge of 1-
1 electron in the s orbital
Alkali metals lose one electron when it becomes an ion.
Rubidium has one valence electron as it an alkali metal.
Lithium is in the second period. It is an alkali metal. It has 2 rings of electrons.
Alkali metal have only one electron on the external shell; the are very reactive and form cations.
One

18 and a half

1, like all other alkali metal atoms.
Lithium is in the second period. It is an alkali metal. It has 2 rings of electrons.
Alkali metal have only one electron on the external shell; the are very reactive and form cations.
All alkali metals have 1 valence electron that is it loses when forming compound, giving it a charge of +1
because it has so many orbitals it has more electrons and it cannot hold onto its electrons as easily and they can easily be snatched away
Na 1s2 2s2 2p6 3sLooks like the one valance electron. This is a Group one metal, an alkali metal.
The key to this answer is the phrase "valence electrons". Alkali metals are in the first column of the periodic table and include elements such as Lithium, Sodium and Potassium. These elements typically lose ONE electron when they participate in a chemical reaction, therefore they have ONE valence electron.
