Want this question answered?
Alkali metals have 1 valence electron.
Alkali metals have 1 valence electron.
Rare earth metals typically have 2 valence electrons.
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.
Valence electrons are the electrons present in the outermost shell of an atom.You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table.For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively.Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively.
Alkali metals have 1 valence electron.
Alkaline earth metals have 2 valence electrons.
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
Alkali metals have 1 valence electron.
The alkali earth elements have TWO valence electrons.
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
Rare earth metals typically have 2 valence electrons.
Copper (Cu) has 2 valence electrons. It is located in the middle group of elements, called Transition Metals, and all transition metals have 2 valence electrons...hope that helped! =D
yes
1 valence electron in alkali metals.
Alkaline earth metals are group 2 elements and have 2 valence electrons.
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.
