What Are Examples of Discrete Molecules?

FAQs Jackson Bowman August 6, 2022

What are discrete molecules in chemistry?

Basically, a “discrete molecule” is a covalent molecule in which the intermolecular forces are really weak, hence the low melting and boiling points of these molecules. The forces acting between these molecules are called van der Waals forces, which are an intermolecular (between molecules) force.

Which elements have discrete molecules?

Elements as discrete molecules:

All diatomic elements exist as discrete molecules: hydrogen, oxygen, nitrogen, fluorine, bromine, iodine and chlorine.

Which compound forms discrete molecules?

Molecular compounds contain discrete molecules held together by shared electrons (covalent bonds).

Is water a discrete molecule?

Discrete Molecules: Diatomic and Other Molecules

Also consider molecules like water, which exist in discrete forms in various physical states like liquid or solid. When ice melts, it changes state but retains its own distinct identity. Other solids would not retain this discrete identity.

Is CO2 a discrete molecule?

So CO2 in a solid phase (basically dry ice) is a discrete molecule.

Is hydrogen a discrete molecule?

Most discrete covalent molecules are diatomic elements: hydrogen (H 2) nitrogen (N 2)

Is sio2 a discrete molecule?

All the atoms are linked together by covalent bonds, making the lattice incredibly strong. This is evidenced by the fact that \[Si{O_2}\] has a melting point of 1713 degrees Celsius (iron melts at 1538 degrees Celsius). So the answer is option D discrete molecules.

Is ammonia a discrete molecule?

Is iodine a discrete molecule?

Iodine is a nonmetallic, almost black solid at room temperature and has a sparkling crystalline appearance. The molecular lattice contains discrete diatomic molecules that also exist in molten and gaseous states. Above 700°C (1,300°F), dissociation into iodine atoms becomes noticeable.

Is SF6 a discrete molecule?

The compound SF6 S F 6 exists as a gas. It contains covalent bonds between molecules. There are discrete molecules… See the full answer below.

Is nitrogen a discrete atom?

The elements hydrogen, oxygen, nitrogen, fluorine, chlorine, bromine and iodine occur in nature as diatomic molecules of their atoms. Most elements, including all metals, do not exist as individual molecules at all, but are instead made up of an extremely large number of atoms bonded together.

Is Potassium a discrete atom?

Is sodium a discrete atom?

Some substances like sodium chloride do not contain individual molecules as their constituent parts. In such compounds, positive (sodium) and negative (chloride) units are arranged in a three-dimensional structure.

Is carbon diamond a discrete molecule?

Diamond is a solid with a covalent network, like a number of other common materials (quartz, graphite, glass, and a whole host of other things). Because they are not discrete molecules – there is no such thing as a “diamond” molecule, nor are there molecules of caffeine, benzoic acid, citric acid, N,N-dimethylaminopyridine, etc.

Is water discrete or continuous?

Often a variable is continuous on one scale but discrete on another. For example, the amount of water used may be discrete if you count individual water molecules, but it is continuous at the scale you are dealing with.
