are there atoms in space?

Space isn't a pure vacuum and as we can see very clearly, there are molecular clouds, dust clouds, gas clouds and remnant atoms of heavy matter from stars that have gone supernova, so for these others to say that “no, there are no atoms in space”, clearly haven't looked at these objects.

An atom is any “thing” that is made up of protons and neutrons and electrons. In an atom, protons and neutrons are bound together and this is the nucleus. ... So basically, the nucleus is the center part of the atom that consists of only bound protons and neutrons, and an atom is the nucleus with electrons.

Volume of Atoms Accounting for the sizes of protons, neutrons, and electrons, most of the volume of an atom—greater than 99 percent—is, in fact, empty space.

The universe is made up of atoms, which contain protons (positively charged particles), neutrons (particles with no charge), and electrons (negatively charged particles). ... Molecules are formed when two or more atoms bond together. If molecules contain atoms of different elements, that substance is known as a compound.

Atoms are not living things; they do not need food, water, and air; and they do not reproduce themselves. Cells are alive. Cells are bigger than atoms. ... Just as atoms have smaller parts called protons, neutrons, and electrons, cells have smaller parts, too.

But, atoms themselves contain many subatomic particles, the three most important of which are protons, neutrons, and electrons. These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number.

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

The Bohr or solar system model of the atom states that atoms consist of a nucleus with a number of electrons in orbits around that nucleus, similar to a solar system. ... Likewise, perhaps our solar system is an "atom" in some larger entity.

Atoms are not mostly empty space because there is no such thing as purely empty space. Rather, space is filled with a wide variety of particles and fields. ... Even if we ignore every kind of field and particle except electrons, protons and neutrons, we find that atoms are still not empty. Atoms are filled with electrons.

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided.

Atoms. Atoms are everywhere! They make up everything around us and are the building blocks of life. They are made up of three different particles - protons, neutrons, and electrons.

The molecules of outer space: Astronomers have found that the dark regions of interstellar space are teeming with molecules, many formed by unusual chemical reactions that rarely occur on the Earth. and planets. many carbon atoms as both chains and rings.

How do atoms exist? Atoms of most elements are not able to exist independently. Atoms form molecules and ions. These molecules or ions aggregate in large numbers to form the matter that we can see, feel or touch.

But looking closer, at the atomic scale, the numbers get even more inconceivable. At this level, it is estimated that the there are between 1078 to 1082 atoms in the known, observable universe.

The space inside the atom is just that, empty space, i.e. vacuum. Air molecules are also made up of atoms with a central core of nucleons and electrons spinning around them. They too have empty space between their nucleons and electrons.

Atoms consist of three types of subatomic particle: protons, neutrons and electrons. The identity of an atom is determined by its proton number or atomic number. ... The electrons are arranged in energy levels or shells: defined areas of space around the nucleus.
