Explain why Scandium is not considered a true transition metal.

By definition, to be a transition metal, is a d block metal, which forms at least one stable ion, with a partially filled 3d shell. Scandium has one stable ion, Sc 3+ , which posses no 3d orbitals, as Scandi...

What is the difference between an ionic bond and a covalent bond?

An ionic bond is the electrostatic attraction between oppositely charged ions formed by atoms that have lost or gained electrons whereas a covalent bond is a shared pair of electrons between two atoms. Ionic...

What is the difference between an ionic and a covalent bond?

A chemical bond joins two atoms together. In covalent bonding, atoms are joined by sharing electrons. For example, water (H 2 O) is created through two OH bonds in each of which, Oxygen and Hydrogen give an ...

Explain why ionic compounds such as potassium sulfide have high boiling points and conduct electricity when dissolved in water?

Such compounds have high boiling points because bonds between the atoms are strong. The boiling point largely depends on electronegativity difference between the atoms - as this difference is greater, so is ...

Explain how the differences in structure between Diamond and Graphite give rise to their different properties

Carbon has 4 electrons in its outer shell, so to fill its outer shell (which can hold up to 8 electrons) and be stable, it wants another 4 electrons. It can do this by sharing its 4 electrons in 4 strong cov...
