Thereof, what is r0 in nuclear radius?
The stable nucleus has approximately a constant density and therefore. the nuclear radius R can be approximated by the following formula, R = nuclear radius in meters (m) r0 = is the radius of a nucleon approx 1.3 fm. A = number of nucleons [or atomic mass number, or Z + N]
Also Know, what is the order of nuclear density? Nuclear density is of the order of 1017kg/m3.
Also question is, why is nuclear density constant?
At that equilibrium point sits all of the nucleons. This means that they are all about the same distance apart and since protons and neutrons have nearly identical mass then there will be the same mass for a given volume regardless of how many nucleons there are, hence the constant density.
Why is iron the most stable nucleus?
The more stable a nucleus is, the more energy is required, per nucleon, to pull the nucleus apart. This stability is caused by the attractive nuclear force between nucleons. Iron 56 is the most stable nucleus. This repulsion between distant protons leads to less binding energy per particle and instability.

Why is nuclear density same for all nuclei?
Why is nuclear density same for all nuclei? This is because density =massvolume, and volume of nucleus varies directly as its mass number.Why is iron the most stable element in the universe?
The more stable a nucleus is, the more energy is required, per nucleon, to pull the nucleus apart. This stability is caused by the attractive nuclear force between nucleons. Iron 56 is the most stable nucleus. This repulsion between distant protons leads to less binding energy per particle and instability.What are nucleons what is their number called?
The mass number (A), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus.Which nucleus is more stable?
It is often stated that 56Fe is the "most stable nucleus", but only because 56Fe has the lowest mass per nucleon (not binding energy per nucleon) of all nuclides.Why are nuclear forces both attractive and repulsive?
The nuclear force does not act on electrons. The fact that protons and neutrons maintain their size while inside a nucleus means that the nuclear force is both attractive and repulsive. If we try to pull two nucleons apart, the attractive nuclear force holds them together, next to each other.Is iron the most stable element?
So, in one word, iron is quite stable. They are considered the most stable elements in the whole periodic table. But their binding energy per nucleon value is less than iron-56. So, they are not stable as iron-56.Is nuclear force attractive or repulsive?
The nuclear force is always attractive, the electromagnetic always repulsive in the nucleus. The distance comes in because the closer charged nucleons approach, the largest the repulsion, the strongest the attraction, the balance depends on the strengths and the distance.What is density of nucleus?
Nuclear density is the density of the nucleus of an atom, averaging about 2.3×1017 kg/m3. The descriptive term nuclear density is also applied to situations where similarly high densities occur, such as within neutron stars.What is meant by atomic number?
Atomic number is the number of protons, and therefore also the total positive charge, in the atomic nucleus. The Rutherford–Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1).What is the size of nucleus?
The nucleus is the center of an atom. It is made up of nucleons called (protons and neutrons) and is surrounded by the electron cloud. The size (diameter) of the nucleus is between 1.6 fm (10−15 m) (for a proton in light hydrogen) to about 15 fm (for the heaviest atoms, such as uranium).What is s mass number?
The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus.Why does strong nuclear force become repulsive?
The strong force needs to be very intense to hold the protons together in such a small volume. The electromagnetic repulsion takes place within the nucleus between like electric charges. These charges are carried by the protons, whose close proximity to each other intensifies this repulsive force.What is meant by isotope?
isotope. An isotope of a chemical element is an atom that has a different number of neutrons (that is, a greater or lesser atomic mass) than the standard for that element. The atomic number is the number of protons in an atom's nucleus.How is the radius of nucleus related to mass number?
Question: How is the radius of a nucleus related to its mass number ? Answer: The radius of a nucleus(r) is proportional to the cube root of its mass number(A). The approximate law is r1 = r2 A^(1/3) ; where r2 = 1.2 x 10^(-15) m.How do you calculate the number of nucleons?
Explanation: Nucleon number is the number of protons plus the number of neutrons.What is nuclear mass?
Nuclear mass refers to the mass of the nucleus, which (you should know that) comprises of only protons and neutrons. Atomic mass refers to the mass of an atom, which includes protons, neutrons and electrons. So for most intent and purposes outside of nuclear physics, nuclear mass and atomic mass is the same.Why is the nucleus positive?
Why the nucleus is positively charged? Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Neutrons have no charge and protons are positively charged. Because the nucleus is only made up of protons and neutrons it is positively charged.Does the nucleus have a high density?
In a nucleus, there are only protons and neutrons, making the density relatively high. In an atom, there is a nucleus, but there are also electrons. The electrons, however, are not tiny bubbles of energy whizzing around the nucleus.How does the nuclear density depends on the size of the nucleus?
Nuclear density is the density of the nucleus of an atom, averaging about 4×1017 kg/m3. The nuclear density for a typical nucleus can be approximately calculated from the size of the nucleus, which itself can be approximated based on the number of protons and neutrons in it.Is nuclear density same for all elements?
Nucleus consists of neutrons and protons. And every element has a unique atomic number which is equal to number of protons, which leads to the fact that the mass of nucleus will be different and since different mass results in different density hence nucleus of all elements does not have same density.Is the nucleus positive?
The nucleus is a small, dense region at the center of the atom. It consists of positive protons and neutral neutrons, so it has an overall positive charge.How dense is a neutron?
Density and pressure The neutron star's density varies from about 1×109 kg/m3 in the crust—increasing with depth—to about 6×1017 or 8×1017 kg/m3 (denser than an atomic nucleus) deeper inside.What is the density of a quark?
