1g - covalent bonding Flashcards
1
Q
what is a covalent bond?
A
a chemical bond that involves the sharing of electrons to form electron pairs between atoms.
2
Q
why do substances with a simple molecular structures are gases or liquids, or solids with low melting and boiling points?
A
Very little energy is needed to overcome the intermolecular forces
3
Q
why do the melting and boiling points of substances with simple molecular
structures increase with increasing relative molecular mass?
A
The stronger the intermolecular attractive forces, the more energy that is required to break them apart
4
Q
do covalent compounds conduct electricity?
A
no
