The element scandium has 21 electrons. However, most of these occupy the inner orbitals. The only electrons in the valence shell are those in the 2s orbital. Since there are two such electrons, scandium has 2 valence electrons.

How many electrons in the outer valence shell of calcium?
There are 2 electrons in valence shell of calcium. :-)
How many electrons are in the valence shell of all column 1 elements?
there are 36 electrons in a valence shell. -cmoney
How many electrons would be present in the valence shell of a iron atom?
Valence electrons are the total amount of electrons on the outermost shell of an atom. Meaning if the last shell has two, the valence electrons are two. But a complete valence shell would hold eight.
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer valence shell.
How many electrons are there in the valence shell of a nitrogen atom?
Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.
How many electrons does an atom have if there are 3 in valence shell?
if you are talking about valence electrons: 3. if you are talking about regular electrons, it differs. there are different atoms in that category. scandium 21 yttrium 39 lutetium 71 lawrencium 103 i hope this helps
