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.
Scandium has 3 valence electrons.
Scandium has 3 valence electrons.
There are 2 electrons in valence shell of calcium. :-)
A silicon atom has 4 electrons in its valence shell.
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.
Scandium has 3 valence electrons.
Scandium has 3 valence electrons.
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
There are 6 valence electrons in the sulfur atom.
Sulfur has six electrons in its valence shell.
Valence electrons are placed in the outermost shell of electrons.
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
2 valence electrons
