write a brief note on the structure of atom.?

Answer 1

hygrogen - on proton in the nucleus and one electron in the first outer enrgey shell

hellium - 2 protons and 2 neutrons in the nucleus, 2 electons in the first energy shell,

there are 7 energy shells, 3 E- for the first, 7 for the second, and so forth i can recall

lithium - 3 protons and nuetrons - 3 electron, do you wnat me to go all the way to uranium #92, well i cant lol

Answer 2

Atoms are made of particles of matter called as fundamental or sub-atomic particles.there are 3 main sub-atomic namely protons,neutrons and electrons.An atom mostly consists of empty space.Almost all of atom's mass is concentrated in a structure at its centre called the nucleus.it consists of proton and neutrons grouped together.
The protons are positively charged particles who has a mass of almost an hydrogen atom.
The neutrons are particles with no charge on them.Its mass is also =2 1hydrogen atom.
The electrons orbit around the nucleus.They are negatively charged.They revolve around the nucleus because it is atrracted to the protns(+ive particles).
An atom is neutral because the protons and electrons are = in number.

Answer 3

Atoms have two parts.Center part is nucleus which is surrounded by electrons.
Nucleus contains protons and neutrons.
Protons are positively charged particles,electrons are negatively charged particles,neutrons are chargeless particles.
Electrons are light mass particles.Proton and neutron approx. have same mass.
Nucleus diameter is in the order of fermi range.Atomic radius is of the order of Angstrom range.

Answer 4

I cannot find a pen small enough to write a note on something as small as the atom's structure. If I could write something, then I would write: Kilroy was here.

Answer 5

proton and electron electomagnetically coupled to a nucleus
