what are 3 main parts of an atom?

Answer 1

An atom is assumed to be the smallest part of any substance.
But the atom actually has more constituents.
The proton, the electron, the neutron are the three main constituents of an atom.
The Proton and Neutron are present in the middle of the atom, in a tiny central core which is called nucleus. Since the proton and the neutron are present in the nucleus, they are called the nucleons.
The electron revolves around the nucleus in many orbits, which again of consist of different paths, which may be circular, or spiral , or dumb-bell shaped, etc.
The proton is positively charged, the electron is negatively charged-.Both have charge of equal magnitude i.e. 1.602 into 10 power -19 coulumbs. However the neutron is neutrally charged or to be more crude, it has no particular charge. The neutron and the proton are the main reasons for the mass of the atom, and the mass of the electron is negligible. Since the atom has equal number of positive and negative charges, it is neutral and hence stable.

3 Parts Of An Atom

Answer 3

The 3 main parts of an atom are:
1. In the centre is Nucleus's.
2. Nuclease has protons
3. There are Electrons revolving round it
The number of the protons & Electrons in the atom is the
same.
Eg: An aluminiun atom has 13 Protons as well as 13
electrons
In an atom the Protons carry Positive charge & the Electrons a negative charge

Answer 4

In chemistry and physics, an atom (Greek ἄτομος or átomos meaning "indivisible") is the smallest particle of a chemical element that retains its chemical properties. (átomos is usually translated as "indivisible." Until the advent of quantum mechanics, dividing a material object was invariably equated with cutting it.) Whereas the word atom originally denoted a particle that cannot be cut into smaller particles, the atoms of modern parlance are composed of subatomic particles:

electrons, which have a negative charge, a size which is so small as to be currently unmeasurable, and which are the least heavy (i.e., massive) of the three;
protons, which have a positive charge, and are about 1836 times more massive than electrons; and
neutrons, which have no charge, and are about 1838 times more massive than electrons.
Protons and neutrons make up a dense, massive atomic nucleus, and are collectively called nucleons. The electrons form the much larger electron cloud surrounding the nucleus.

Atoms can differ in the number of each of the subatomic particles they contain. Atoms of the same element have the same number of protons (called the atomic number). Within a single element, the number of neutrons may vary, determining the isotope of that element. The number of electrons associated with an atom is most easily changed, due to the lower energy of binding of electrons. The number of protons (and neutrons) in the atomic nucleus may also change, via nuclear fusion, nuclear fission or radioactive decay, in which case the atom is no longer the same element it was.

Atoms are electrically neutral if they have an equal number of protons and electrons. Atoms which have either a deficit or a surplus of electrons are called ions. Electrons that are furthest from the nucleus may be transferred to other nearby atoms or shared between atoms. By this mechanism atoms are able to bond into molecules and other types of chemical compounds like ionic and covalent network crystals.

Atoms are the fundamental building blocks of chemistry, and are conserved in chemical reactions.

Answer 5

They are Protons, Neutron and Electrons.

Protons:
Charge: +1
Weight: 1

Neutrons:
Charge: 0
Weight: 1

Electrons:
Charge: -1
Weight: 1 over 1840 (as a writen fraction)

The postive, negative and neutral charges combine to make the atom have a neutral charge.

Answer 6

Hi There,

Well if you are speaking about atom, then those three parts are Electron, Proton and Neutron. But, Dear That's not all . Today Science have stepped farther and farther. These three things are not the only ones! There are many more discovered and being discovered. I am telling this 'coz I have researched it! Hope this answers your question!

Take care!

Answer 9

An atom is the smallest unit of any matter.An atom has a nucleus at it's centre and there is some space surrounding the nucleus.The nucleus contains positively charged particles called protons and neutrally charged particles called neutrons.Outside the nucleus , negatively charged particles called electrons are present.The number of protons and the number of electrons are equal.Hence the charges of the particles(i.e electrons and protons)are cancelled out ny each other.Thus as a whole an atom is neutral(i.e.no net charge).Recently it has also been discovered that protons further contain "quarks" in them.

Answer 10

Protons - +ve charge
Neutrons - neutral
Electrons - -ve charge.

Protons and neutrons combinely form the nucleus and electrons revolve around the nucleus.
This whole structure is called an atom
