What are examples of discrete molecules?

What are examples of discrete molecules?

Molecular compounds contain discrete molecules, which are held together by sharing electrons (covalent bonding). Examples are water, which contains H2O molecules; methane, which contains CH4 molecules; and hydrogen fluoride, which contains HF molecules.

Is hydrogen a discrete atom?

Discrete Molecules: Diatomic and Other Molecules Several of the nonmetals exist as gases at room temperature and as diatomic molecules: H2, N2, O2, F2, Cl2, I2 and Br2. These act as discrete molecules.

What is a discrete atom?

The discrete forms are either monoatomic—meaning that they exist as separate atoms (such as He and Ne) with no covalent bonds between them (although they do interact via van der Waals interactions)—or diatomic molecules (such as H2, N2, O2, and F2), meaning that they exist as molecules that have only two atoms.

Which element has discrete covalent molecules?

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

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. The forces which act between these molecules are called Van Der Waals forces which is a intermolecular (between molecules) force.

Is Potassium a discrete atom?

So, xenon, and argon exist as discrete atoms that exist in the gas phase. Barium and potassium are non-molecular species, which exhibit metallic bonding with no molecular boundaries.

Is CO2 a discrete molecule?

Molecular compounds are chemical compounds that take the form of discrete molecules. Examples include such familiar substances as water (H2O) and carbon dioxide (CO2) (Figure 3.1. 1).
