What alkali metal has an atomic radius of 238 pm?
The alkali metal with an atomic radius of 238 pm is potassium (K). Its large atomic radius is due to the added electron shells compared to other alkali metals in the same period.
What are two elements with one electron in their outer shells?
Any two of the alkali metals, group I of the periodic table: Li, Na, K, Rb, Cs and one extra: the only non metal in group I Hydrogen (H2).
The outer electron configuration of an alkali metal has?
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
Does rubidium have one valence electron?
Yes. Rubidium is an alkali metal, and all alkali metals have one valence electron.
What is like a alkali metal but has 1 electron?
Hydrogen.

What alkali metal has two energy levels?
Lithium is the alkali metal that has two energy levels in its electron configuration. Its electron configuration is [He] 2s¹.

Yes. Rubidium is an alkali metal, and all alkali metals have one valence electron.
What is like a alkali metal but has 1 electron?
Hydrogen.
Not an alkali metal with only 1 electron?
Hydrogen
Is scandium a alkali metal?
No, scandium is not an alkali metal. It is actually classified as a transition metal due to its electron configuration and position on the periodic table.
What happens to the valence electron in an alkali metal when it combines with a halogen gas?
This electron is lost.
Is na an element?
Yes. Na is the chemical symbol for Sodium. Sodium is an Alkali Metal in Group 1 of the Periodic Table. Sodium has the atomic number 11, has 3 electron shells with 1 electron in the outer shell.
What is the group that has one electron in its outer level?
alkali metal
What charge do alkali metals form when they react with a halogen?
here r the possisble answers: both atoms lose 1 electron a covalent bond forms metal gains an electron and the nonmetal loses an electron metal loses an electron and non metal gains an electron
