how is atom formed?

Answer 1

The current view is that atoms are made up of protons and neutrons (which in turn are made up of quarks and gluons) and electrons. The protons and neutrons are at the central core called the nucleus, and the electrons revolve around it, being held in orbit by the electromagnetic force between the negatively charged electrons and the positively charged protons in the central nucleus. It is very much like the solar system with the sun at the center and the planets revolving around it. They were formed right after the "Big Bang" when our known universe originated from pure energy some billions of years ago. The energy was converted to the elementary particles (quarks, gluons, leptons etc...) from which protons and neutrons were formed. From these, atoms of different elements were produced.

What is an atom? What are atoms made of?

Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you.

Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.

Protons and neutrons are both composed of other particles called quarks and gluons. Protons contain two 'up' quarks and one 'down' quark while neutrons contain one 'up' quark and two 'down' quarks. The gluons are responsible for binding the quarks to one another.

Answer 2

In the process of atom formation, the carriers of characteristics of the nucleus and the electrons influenced each other even after they had achieved equilibrium. This happened while electrons were circling the nuclei, attracting and repelling each other, so that the nucleus had to counterbalance the encircling influence at every position, making it difficult for the nucleus to stay still in its place. This condition made the nucleus vibrate and the electrons sinuous. Concentration was thus the beginning of change, movement, temperature and time.

Answer 3

Composition of the Atom



The atom consists of a tiny nucleus surrounded by moving electrons. The nucleus contains protons, which have a positive charge equal in magnitude to the electron's negative charge. The nucleus may also contain neutrons, which have virtually the same mass but no charge.

Answer 4

atom is made of protons,neutrons and electrons.protons have a positive charge,nuetrons are nuetral and electrons have a negative charge.there are same numbers of protons and electrons in an atom.they nullify each other and hence the atomic charge of the atom is zero.

Answer 5

All of the hydrogen in the Universe and some of the helium were produced in the Big Bang.

All other elements are created in two ways:

1) nuclear fusion (naturally in stars or artificially in some kind of fusion reactor)
2) nuclear fission - decay of one radioative element into another.
