I believe 4s2 is the distinguishing (last) electron
Scandium is a non metal element. There are 21 electrons in a single atom.
Scandium has 2 valence electrons.
+s
16
Sc is a 3d element. It has 21 protons and 21 electrons.
Sc is a s block element. There are 1.16 molesin 52.3 grams.
one valence electron
The atomic number for the element gold is 79. This means there are 79 electrons in an atom of this element.
the answer is 28
Sc is a 3d element. It has 21 protons and 21 electrons.
As the elemental metal sodium has 11 (eleven) electrons; the same number as the protons, and the atomic no.(Z). However, sodium will readily lose one(1) electron to form the sodium cation (Na^(+)) . When it is the sodium cation it has 11 protons, but only 10 electrons.
The Element Neon has 10 protons and 10 electrons.
8 electrons
Thorium has 90 electrons.
8 electrons
43 electrons :)
4 electrons, 2 valence electrons
