Yes, it is correct.
Alkali metals have one valence electron.
one valence 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 metals lose one electron in chemical reactions.
Yes. Rubidium is an alkali metal, and all alkali metals have one valence electron.
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
Alkali metals have 1 valence electron.
they have one valence electron (not proton) that is involved in chemical bonding.
hydrogen and the alkali metals lithium, sodium, potassium, rubidium, cesium, and francium all have one valence electron.
alkali metals have 1 electron in there outer valence shell. I remember that alkali and alkaline go with columns 1 & 2 of the periodic table alphabetically. Alkali then alkaline. Alkali metals have 1 valence electron. Alkaline metals have 2 valence electrons.
Highly reactive metals with one valence electron are known as Alkali metals.
Alkali metals, such as sodium and potassium, are characterized by having a single valence electron and very reactive atoms. They readily lose this outer electron to form +1 cations in chemical reactions.
