Question

lewis dot structure of scandium​

Answer 1

${\huge{\sf{\green{\underline {\underline {Answer }}}}}}$

The one electron in the 3d orbital and the two electrons in the 4s orbital are scandium's three valence electrons. Scandium can lose one, two or all three valence electrons to become Sc+1, Sc+2 or Sc+3, respectively. The +3 oxidation state is the most common. Scandium Z=21 has an electronic configuration [Ar] 4s 3d......

Since the Lewis electron dot diagrams are based on the number of valence electrons, it would hold true that the elements in the same group would have the same electron dot diagram. In other words, if every element in Group 1A has 1 valence electron, then every Lewis electron dot diagram would have one single dot.....

Answer 2

Step 1: Find the Total Number of Valence Electrons

Step 2: Find the Number of Electrons Needed to Make the Atoms "Happy"

Step 3: Determine the Number of Bonds in the Molecule

Step 4: Choose a Central Atom

Step 5: Draw a Skeletal Structure

Step 6: Place Electrons Around Outside Atoms

Step 7: Place Remaining Electrons Around the Central Atom
