# What is the radius of a c12 nucleus?

## What is the radius of a c12 nucleus?

The nuclear radius of carbon-12 is 2.7 x 10-15 m while the size of the atom from the periodic table is about 0.9 x 10-10 m, about 33,000 times larger!

## What is the diameter of a carbon nucleus?

0.3 nm
Carbon in diamond form has a different density than graphite because of its atomic lattice structure. But this estimate at least establishes the kind of atomic sizes expected. A typical atomic diameter is 0.3 nm.

What is the radius of nucleus?

It is found that nuclear radii range from 1-10 ´ 10-15 m. This radius is much smaller than that of the atom, which is typically 10-10 m. Thus, the nucleus occupies an extremely small volume inside the atom.

### What is size of nucleus?

The diameter of the nucleus is in the range of 1.70 fm (1.70×10−15 m) for hydrogen (the diameter of a single proton) to about 11.7 fm for uranium.

### How do you calculate the size of the nucleus?

The formula to measure the size of nucleus is:

1. R = R0A1/3.
2. Where R0 = 1.2 * 10-15 m.
3. mnucleon ~ ⅙ * 10-27 kg.
4. Volume = 4/3 * π * R3, Here R = R0A1/3.
5. Density of nuclear matter ρ = mnucleon/Volume ~ 2 * 1017 kg/m3.

How do you find the radius of an atom?

The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance.

## How is the radius of a nucleus related to its mass number Class 12?

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.

## What is the radius of a neutron?

The neutron has a mean square radius of about 0.8×10−15 m, or 0.8 fm, and it is a spin-½ fermion.

What is the size of a nucleolus?

0.5 to 5 µm
The typical nucleus boasts 2–5 nucleoli, ranging in size from 0.5 to 5 µm in diameter.

### In which unit radius of nucleus is measured?

femtometre
measuring nuclear sizes is the femtometre (fm), which equals 10−15 metre. The diameter of a nucleus depends on the number of particles it contains and ranges from about 4 fm for a light nucleus such as carbon to 15 fm for a heavy nucleus such as lead.

### What is actual size of nucleus?

What is the size of a cell nucleus?

approximately 6 micrometres
The nucleus is the largest organelle in animal cells. In mammalian cells, the average diameter of the nucleus is approximately 6 micrometres (µm).

## What is the radius of a single atom?

Under most definitions the radii of isolated neutral atoms range between 30 and 300 pm (trillionths of a meter), or between 0.3 and 3 ångströms. Therefore, the radius of an atom is more than 10,000 times the radius of its nucleus (1–10 fm), and less than 1/1000 of the wavelength of visible light (400–700 nm).

## What is the radius of an element?

The atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron.

What is atomic radius of carbon?

170 pmCarbon / Van der Waals radius

### How much smaller is a nucleus than an atom?

ten thousand times smaller
Nuclei are very dense and extremely small. They contain more than 99.9% of the mass of an atom and are ten thousand times smaller than an atom! The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral.

### What is the radius of A nucleus of mass number 216?

2×10−15m.

How is radius of nucleus related to mass number *?

R=R0A1/3.
