Chemical Compounds Flash Cards

Ionic compounds conduct electricity when melted.

• They allow electricity to flow when in liquid form.

• They do not conduct electricity in any state.

• They only conduct electricity when solid.

• They conduct electricity better than metals.

Electrons are found in energy levels around the nucleus of the atom.

• Electrons occupy specific energy levels.

• Electrons are randomly distributed in the atom.

• Electrons can exist anywhere in the atom.

• Electrons are only found in the nucleus.

Molecular compounds have lower melting points.

• They can be solid, liquid, or gas at room temperature.

• They have higher boiling points than ionic compounds.

• They are always gases at room temperature.

• They are typically found in a crystalline solid state.

Ionic compounds are brittle solids.

• They can break or shatter easily.

• They are always liquid at room temperature.

• They conduct electricity in solid form.

• They have a low melting point.

Ionic compounds are not electrically conductive as solids.

• They do not allow electricity to flow in solid form.

• They conduct electricity in solid form.

• They are good conductors of electricity when solid.

• They allow electricity to flow freely in solid state.

The most important electrons are in the highest energy ring.

• These electrons play a key role in chemical bonding.

• These electrons are responsible for the mass of the atom.

• These electrons are always found in the nucleus.

• These electrons determine the color of the element.

Electron cloud in polar covalent bonds

• The electron cloud is shared equally in polar covalent bonds.

• The electron cloud is shared unequally in polar covalent bonds.

• The electron cloud is not involved in polar covalent bonds.

• The electron cloud is completely transferred in polar covalent bonds.

There is a recurring pattern to how the electrons are arranged.

• Electron arrangement

• Electron configuration

• Electron distribution

• Electron sequence

Structure of molecular compounds.

• They are crystalline solids.

• They are amorphous solids.

• They are gases at room temperature.

• They are metallic in nature.

Non-polar covalent bond

• A type of bond where there is equal attraction for electrons within the bond and equal sharing of the electron cloud.

• A bond formed between two atoms with a significant difference in electronegativity.

• A bond that involves the transfer of electrons from one atom to another.

• A bond characterized by unequal sharing of electrons between two atoms.
