## 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:

- R = R0A1/3.
- Where R0 = 1.2 * 10-15 m.
- mnucleon ~ ⅙ * 10-27 kg.
- Volume = 4/3 * π * R3, Here R = R0A1/3.
- 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.
