## How many electrons are present in the universe?

The current estimate is that there are 100000000000000000000000000000000000000000000000000000000000000000000000000000000 (that’s 1 followed by 80 zeros!) atoms in the universe. Most atoms in the universe are hydrogen, so have 1 proton and 1 electron, so the number of electrons in the universe is probably similar.

## How many atoms are in the universe?

The universe is a vast range to consider and while knowing that all matter is composed of extremely small particles called atoms, it is estimated that there may be 1078 to 1082 atoms in the known universe.

## How many electrons are in the earth?

How many electrons in earth? – Quora. The answer is 1.75 x 10^51.

## Is it possible that there is only one electron in the universe?

It is improbable that there is only 1 electron since there are many protons that require several electrons to neutralize the charge on the molecules.

## Are there 52 atoms in the universe?

There are between 1078 to 1082atoms in the observable universe.

## Who has 31 electrons?

Gallium atoms have 31 electrons and the shell structure is 2.8.

## What are 90% of all atoms in the universe?

Today hydrogen is estimated to account for 90% of all atoms in the universe, and it is essential to the material world.

## Is the atom 99.9% space?

Although, by volume, an atom is mostly empty space, dominated by the electron cloud, the dense atomic nucleus, responsible for only 1 part in 10^15 of an atom’s volume, contains ~99.95% of an atom’s mass.

## How big is the universe?

The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).

## How big is an electron?

It is concluded that the diameter of the electron is comparable in magnitude with the wave-length of the shortest γ-rays. Using the best available values for the wave-length and the scattering by matter of hard X-rays and γ-rays, the radius of the electron is estimated as about 2 × 10−10 cm.

## Who has 27 electrons?

The atom cobalt has 27 electrons.

## Who has 17 electrons?

For example, every chlorine atom has 17 electrons and 17 protons; its atomic number is 17.

## Who has 12 electrons?

Magnesium, in its elemental form, has 12 protons and 12 electrons.

## Who has 8 electrons?

So… for the element of OXYGEN, you already know that the atomic number tells you the number of electrons. That means there are 8 electrons in an oxygen atom.
