they all have a differnet number of electrons, but all have a charge of 1-
1 electron in the s orbital
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.
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.
ALKALI METAL OF FIRST GROP HAS 1 8ALENCE ELECTRON LIKE Na,K ETC. AND 2ND GROP ELEMENT HAS 2 LIKE Ca,Mg etc
One
1 electron in the s orbital
18 and a half

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.
ALKALI METAL OF FIRST GROP HAS 1 8ALENCE ELECTRON LIKE Na,K ETC. AND 2ND GROP ELEMENT HAS 2 LIKE Ca,Mg etc
1 valence electron in alkali metals.
1, like all other alkali metal atoms.
NaCl - table salt (there are many salts) Na - Alkali metal Cl - Halogen
