Why do galaxies look like atoms?

Hubble View of a Galaxy Resembling an Atomic Nucleus Its peculiar appearance is the result of a collision between two galaxies that took place about a billion years ago, which ripped both galaxies apart.

Why do atoms look like solar system?

According to the Bohr or solar system model of matter, every atom consists of a nucleus with a certain number of electrons rotating about the nucleus in their orbits. This is similar to the configuration of a solar system, with a large sun in the center and planets rotating in orbits around the sun.

What is similar about the structure of all atoms?

Yes, all things are made of atoms, and all atoms are made of the same three basic particles – protons, neutrons, and electrons. You know that the number of protons in an atom determines what element you have. For instance hydrogen has one proton, carbon has six.

Why does an atom gain or lose electrons?

Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions.

What does an atom look like inside?

Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. Most of an atom is empty space.

How are atoms both similar and different?

The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as “isotopes”.

How are atoms of the same element similar?

Atoms of the same element consist of the same atomic number that is number of protons or electrons and different mass number that is number of neutrons. This variation or change in the number of neutrons in an atom gives rise to different isotopes of an element. An element with different isotopes occurs in nature.
