calcium
Metalloids typically have 3 to 6 valence electrons. This intermediate number of valence electrons allows metalloids to exhibit both metal and non-metal characteristics.
Nonmetals attract electrons.
Calcium is a non metal element. There are 20 electrons in a single atom.
Zinc has two valence electrons.
Calcium has a total of two valence electrons.
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
All alkali earth metals have 2 valence electrons.
Beryllium is the alkaline earth metal that has 2 valence electrons.
There are 2 valence electrons in Barium.
Metalloids typically have 3 to 6 valence electrons. This intermediate number of valence electrons allows metalloids to exhibit both metal and non-metal characteristics.
Two valence electrons.
Nonmetals attract electrons.
they are making metal bonds. that is the purpose.
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.
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
Beryllium has two valence electrons.
Calcium is a non metal element. There are 20 electrons in a single atom.
