Covalent Bonds Flashcards
State the definition of a covalent bond.
A strong bond between two non-metals formed by a shared pair of electrons.
State the definition of a molecule.
Two or more atoms bonded together.
A single covalent bond is made up of…
Two electrons : one from one atom and one from another.
A double covalent bond is made up of…
Four electrons : two from one atom and two from another.
What physical state are simple covalent molecules at room temperature?
Gases or liquids.
Are the intermolecular forces between simple covalent molecules strong or weak?
Weak
How does the strength of intermolecular forces changes with the size of the molecule.
The larger the molecule the stronger the intermolecular forces.
Can simple covalent molecules conduct electricity?
No.
What are properties of simple covalent molecules?
They have low melting and boiling points, they cannot conduct electricity.
