1g - covalent bonding Flashcards
what is the difference between covalent bonds and ionic bonds?
covalent: electrons are shared between atoms
ionic: electrons are transferred from one atom to another
what is represented by a short straight line between two atoms?
a covalent bond
true or false?
simple covalent molecules conduct electricity.
false.
they do not conduct electricity as they do not contain free electrons
what is a covalent bond?
it is a type of chemical bond where atoms share pairs of electrons with each other
what are intermolecular forces
the weak forces of attraction that exist between individual molecules in a covalent substance.
true or false?
covalent bonds involve the transfer of electrons.
false.
they share instead of transfer electrons
what type of materials form a covalent bond?
non-metals
what makes each atom more stable in a covalent bond?
it allows each atom to achieve an electron configuration similar to a noble gas
what is formed when a group of two or more atoms covalent bond together?
a compound / molecule
true or false?
dot and cross diagrams can represent giant covalent structures
false.
dot and cross diagrams are used to represent only small covalent molecules with a fixed number of atoms
what are simple molecular?
a small covalent molecule with a fixed number of atoms
what are diatomic molecules?
they are molecules composed of two atoms.
what are inorganic molecules?
simple molecules that do not contain carbon atoms
what is an organic molecule?
a simple molecule that contains carbon and hydrogen atoms
