nucleon number

USAGE SUMMARY

The phrase "nucleon number" is correct and usable in written English.
It is typically used in scientific contexts, particularly in chemistry and physics, to refer to the total number of nucleons (protons and neutrons) in an atomic nucleus. Example: "The nucleon number of carbon-12 is 12, indicating it has 6 protons and 6 neutrons."

Since protons and neutrons are also known to arrange themselves in closed nuclear shells, the same effect happens at nucleon shell closures, which happen at specific nucleon numbers often dubbed "magic numbers".

Here, attempts are made to conceptualize an integrated nuclear model capable of providing all nuclear characteristics such as binding energy per nucleon, magic number, excited states, and magnetic moments.

Journal of Theoretical and Applied Physics

The muons interact with electrons and nucleons and the number of muon interactions with matter increases proportional to the "density length" (density × path length).

So, I think it is safe to say that the number of nucleon particles are relatively stable over long periods of time - depending on your definition of "long".

Huffington Post

Then, the number of nucleons that born at an element, rising of nucleons from an element to the bottom of column and molar velocity of solid are given by the following equations, respectively: no = B 0 · ρ l · π · d R 2 · ( d z ) 4 (21) r = π 6 G × 10 - 6 U l × ( h - z ) 3 (22) S = 4 × ρ s π · d R 2 · M s × ∑ ( no × r ).

Applied Petrochemical Research

As the number of nucleons in a nucleus increases beyond about 40, the number of protons must be diluted with an excess of neutrons to maintain relative stability.

Expert writing Tips

Best practice

When writing about nuclear properties, use "nucleon number" or "mass number" to clearly indicate the total count of protons and neutrons in a nucleus. Be precise and avoid ambiguity.

Common error

Avoid using "nucleon number" interchangeably with "atomic number". Atomic number refers only to the number of protons, while nucleon number includes both protons and neutrons.

Linguistic Context

The phrase "nucleon number" functions as a noun phrase, specifically a technical term in nuclear physics and chemistry. It identifies a fundamental property of an atomic nucleus: the total count of protons and neutrons, as evidenced by Ludwig's examples.

Ludwig's WRAP-UP

In summary, "nucleon number" is a noun phrase functioning as a technical term within the scientific domains of nuclear physics and chemistry. As Ludwig AI confirms, this phrase, synonymous with mass number, precisely quantifies the total count of protons and neutrons in an atomic nucleus. It maintains a formal and scientific register, predominantly used in academic and technical contexts, but also mentioned in encyclopedias and news. While not a frequently used term (rare), it's essential for clearly communicating about atomic structure and isotopes. Related phrases like "mass number", "atomic mass number", or "number of nucleons" offer alternative ways to express the same concept. Remember to distinguish "nucleon number" from "atomic number" to avoid confusion.

More alternative expressions

Phrases that express similar concepts, ordered by semantic similarity:

mass number

This is the most direct synonym, referring to the total number of protons and neutrons in an atomic nucleus.

atomic mass number

Similar to mass number, but sometimes used to emphasize the atomic context.

number of nucleons

This phrase explicitly states what the number represents, providing clarity.

total nucleon count

Emphasizes the counting aspect of the nucleons in the nucleus.

nuclear mass number

Highlights the number's role in determining the mass of the nucleus.

nucleon content

Refers to the composition of the nucleus in terms of nucleons.

baryon number

Baryon number includes all baryons, but in the context of a nucleus, it's equivalent to nucleon number.

number of protons and neutrons

Breaks down the nucleon number into its constituent parts.

isotope number

Implies the specific number of nucleons that define an isotope.

atomic weight

While technically different (atomic weight is relative), it's often used in a similar context.

FAQs

What is the difference between mass number and "nucleon number"?

The terms mass number and "nucleon number" are synonyms and refer to the total number of protons and neutrons in an atomic nucleus. They can be used interchangeably.

How is the "nucleon number" related to isotopes?

Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons, leading to different "nucleon numbers". For example, carbon-12 and carbon-14 are isotopes with nucleon numbers 12 and 14, respectively.

What is the significance of the "nucleon number" in nuclear reactions?

In nuclear reactions, the total "nucleon number" is conserved. This means that the sum of the nucleon numbers of the reactants must equal the sum of the nucleon numbers of the products.

How does "nucleon number" relate to atomic mass?

The "nucleon number" is a whole number representing the total count of nucleons. Atomic mass, however, is the actual mass of an atom, typically measured in atomic mass units (amu), and it accounts for the mass of the electrons as well as slight differences in the masses of protons and neutrons due to binding energy.
