## How do you find the diameter of a hydrogen atom?

Hint: Hydrogen atom is the first element of the modern periodic table and therefore has the lowest value of atomic number. The atomic diameter of a hydrogen atom can be determined by finding out its radius and multiplying it by two.

**How is the diameter of an atom determined?**

The size of an atom is difficult to describe because atoms have no definite outer boundary. To overcome this problem, the size of an atom is estimated by describing its radius. In metals, this is done by measuring the distance between two nuclei in the solid state and dividing this distance by 2.

### What is the diameter of hydrogen atom in the ground state?

The radius of hydrogen atom in ground state is 0.53 angstrom.

**What is the diameter of a hydrogen atom in scientific notation?**

The diameter of a hydrogen atom is about 5×10^-11 meter.

#### What is the diameter of a hydrogen molecule?

List of diameters

Molecule | Kinetic diameter (pm) | |
---|---|---|

Name | Formula | |

Hydrogen | H2 | 289 |

Helium | He | 260 |

Methane | CH4 | 380 |

**What is the diameter of a proton?**

The team reports that protons measure 0.833 femtometers in diameter (a femtometer is one-trillionth of a millimeter). This measurement is roughly 5\% percent smaller than the previously-accepted radius value.

## Is the diameter of a hydrogen atom is larger than a millimeter?

A hydrogen atom has a diameter of about 10.1 nm.

**What is the size of an atom?**

**Size: **Atoms have an average radius of about 0.1 nm. About 5 million hydrogen atoms could fit into a pin head. The nucleus of an atom is 10,000 times smaller than the atom.

### What is the size of an atom in scientific notation?

about 0.00000003 centimeters

The average size of an atom is about 0.00000003 centimeters across. The length of these numbers in standard notation makes them awkward to work with. Scientific notation is a shorthand way of writing such numbers. The sign of the exponent tells which direction to move the decimal.

**What is the size or diameter of a molecule?**

The diameter of a molecule, assuming it to be spherical; has a numerical value of 10-8 centimeter multiplied by a factor dependent on the compound or element.

#### Do all hydrogen atoms have approximately the same diameter?

The diameter of an atom for this type of hydrogen differs from the more common type. Atoms vary greatly in weight, but they are all about the same size.

**Is an oxygen atom bigger than a hydrogen atom?**

Oxygen atom is bigger than Hydrogen in terms of structure and number of electrons. Hydrogen atom has only one electron to use for making bonds with other atoms whereas Oxygen atom has eight electrons(therefore bigger size)to use for making strong bonds with other elements. This is the reason why Oxygen atom is heavier.

## What is the radius of a hydrogen atom?

A hydrogen nucleus has a radius of 1 x 10-15 m and the electron is about 5.4 x 10-11 m from the nucleus. Assume the hydrogen atom is a ball with a radius of about 5.4 x 10-11 m and the nucleus is a ball with a radius of 1 x 10-15 m.

**What is the size of hydrogen atom in meters?**

The hydrogen nucleus has a diameter of approximately 2.40×10^-15 m. (a) For a scale model, represent the diameter of the hydrogen atom by the length of an American football field (100 yards = 300 ft) and determine the diameter of the nucleus in millimeters.
