What Elements Are Discrete Molecules?

FAQs Jackson Bowman July 24, 2022

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

What are the discrete molecules?

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 are discrete atoms?

Individual Molecular Elements

A small group of nonmetal atoms held together by strong covalent bonds. Five of these discrete molecular elements are described as being diatomic; H2, F2, Cl2, O2 and N2 and all are gases at room temperature.

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.

How do you know if a molecule is discrete?

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.

Is CO2 a discrete molecule?

Molecular compounds are chemical compounds that take the form of single molecules. Examples of this are well-known substances such as water (H2O) and carbon dioxide (CO2) (Figure 3.1.1).

Are ionic molecules discrete?

Because an ionic compound does not consist of individual, discrete molecules, it cannot be properly symbolized using a molecular formula. Instead, ionic compounds must be symbolized by a formula that gives the relative number of their constituent ions.

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 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 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 Potassium a discrete atom?

So xenon and argon exist as discrete atoms that exist in the gas phase. Barium and potassium are nonmolecular species that exhibit metallic bonding without molecular boundaries.

Is chlorine a discrete molecule?

Elements as discrete molecules:

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

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.
