How far across is a hydrogen atom?

A hydrogen atom has a diameter of approximately 1.06×10−10 m 1.06 × 10 − 10 m , as defined by the diameter of the spherical electron cloud around the nucleus.

How far from the nucleus in a is the electron in a hydrogen atom if it has energy of 0.850 eV?

2.39Å
How far from the nucles is the electron in a hydrogen atom if it has energy of -0.850 eV? 2.39Å

How far away are electrons from the nucleus?

The Bohr radius, is the estimated distance between protons in the nucleus and electrons – but electrons aren’t solid, stationary particles… The simple answer would be about one-twentieth of a nanometre.

What is the radius of a hydrogen nucleus?

The single proton that forms the nucleus of the hydrogen atom has a radius of approximately 1.0 X 10-13 cm.

How does the size of the nucleus compared to the size of the atom?

The diameter of a nucleus is about 2 × 10 -15 m and the diameter of an atom is 1 × 10 -10 m. Therefore the atom is 5 × 10 4 larger than the nucleus. The model of the atom must be 5 × 10 4 times larger than this.

How small is the nucleus compared to the size of an atom?

The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.) Mass. Although it is very small, the nucleus is massive compared to the rest of the atom.

What is the size of the nucleus of a hydrogen atom?

The nucleus of a hydrogen atom (just a single proton) is 1.75 femtometers (1 femtometer = 1E-15 meters), while the nuclei of heavier atoms is up to about 15 femtometers.

How far away is an electron from the nucleus?

Based on my own knowledge, if the nucleus was the size of a football, the electron (assuming its rough location within the cloud), would be 1 km away. Therefore, if the nucleus was the size of a golf ball, the electron would be roughly 300 meters away.

What is the radius of the Sun?

Its radius , R S = 7 x 10 10 cm. If the sun were a large grapefruit (r~ 7 cm), the Earth would be a pinhead 15 meters away. The Solar System; Sizes are to scale, but distances are not. The Stars – The nearest star, Alpha Centauri, is a triple star system in the constellation Centaurus.

What would an atom look like if it was expanded?

Rather, it’s an area of probability, in which the size of the atom is defined by the probability that an electron will be found at a certain distance from its nucleus. So the answer is, if you expanded an atom to a size we could see, it wouldn’t look much like anything.
