Question

can you tell me something about atoms structure

Answer 1

Atoms consist of electrons surrounding a nucleus that contains protons and neutrons.
A atom looks like the solar system with all the planets as electrons and the sun as the nucleus...
Electron have negative charge.
Protons have positive charge.
Neutrons have no charge.

Answer 2

Hello...

the structure of an atom, theoretically consisting of a positively charged nucleus surrounded and neutralized by negatively charged electrons revolving in orbits at varying distances from the nucleus, the constitution of the nucleus and the arrangement of the electrons differing with various chemical elements.

Protons and neutrons are held together rather closely in the center of the atom. Together they make up the nucleus, which accounts for nearly all of the mass of the atom.

Electrons move rapidly around the nucleus and constitute almost the entire volume of the atom. Although quantum mechanics are necessary to explain the motion of an electron about the nucleus, we can say that the distribution of electrons about an atom is such that the atom has a spherical shape.

Atoms have sizes on the order of 1-5 � (1 angstrom = 1 � = 1 � 10-10 m) and masses on the order of 1-300 amu.

To put the mass and dimensions of an atom into perspective consider the following analogies. If an atom were the size of Ohio stadium, the nucleus would only be the size of a small marble. However, the mass of that marble would be ~ 115 million tons.

hope it helps...
