scandium scandium
Scandium's typical oxidation state is +3 Phosphate (PO4) is -3 charge so the formula is: ScPO4
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's atomic number is 21. Therefore, neutral scandium has 21 protons and 21 electrons. Scandium's only stable isotope is 45Sc, which has 45 - 21 = 24 neutrons.
oxidation number of I is -1. oxidation number of F is +1.
scandium scandium
This compound is made from Scandium and chlorine ions. Scandium is a metal while Chlorine is a non metal. So the metallic ion is the scandium(ii) ion.This is an ionic compound between scandium and chlorine. Scandium is the metal involved. The oxidation number of Sc is +2.
Scandium's typical oxidation state is +3 Phosphate (PO4) is -3 charge so the formula is: ScPO4
The first transition metal is scandium, Sc, with atomic number 21.
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 49 has 24 protons because it is scandium (which has an atomic number of 21) plus 28 neutrons.
The atomic number of scandium is 21. So it has 21 protons and 21 electrons. Number of neutrons depends on the isotope. Number of neutrons = Mass number - Atomic number Sc-45 isotope has 24 neutrons
The atomic number of scandium (Sc) is 21. The atomic weight of Sc is 44.95591 grams per mole.
Scandium's atomic number is 21. Therefore, neutral scandium has 21 protons and 21 electrons. Scandium's only stable isotope is 45Sc, which has 45 - 21 = 24 neutrons.
oxidation number of I is -1. oxidation number of F is +1.
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
Scandium is a meta element. Atomic mass of it is 45. Atomic number of it is 21.
