What is the arrangement of an atom?

EDIT: Okay, that's pretty random and not at all helpful, try this:

Atoms are made up of 3 different particles, called electrons, protons and neutrons.

Electrons are very small, very light particles with a negative electrical charge, and Protons are much larger, much heavier particles with a positive electrical charge. Neutrons are large and heavy, like the protons, but have no electrical charge.

Each atom is made up of a mixture of these particles. Protons and neutrons are inside the nucleus of the atom, whilst the electrons orbit around it, in clouds. The electrons are organised in layers, called orbitals. The first level is called the 1s orbital, and contains 2 electrons. The second and third levels are the 2s and 2p orbitals and each contain 2 electrons. The 4th level is the 3s orbital, then the next is 3p etc. Logically, at this point, the next orbital would be the 3d orbital, but this has a higher energy than the 4s, so the 4s fill first, then the 3d, then the pattern continues.

Hope this helps,

Answer 2

Atom has 3 main parts i.e protons(positive charge),neutrons(no charge),electrons(negative charge).the protons and neutrons combine to form nucleus which is the center part of the atom with net charge of positive and the electrons are arranged around the nucleus in the atomic orbitals so that the positive charged nucleus holds the negative charge electrons to revolve around it and that's how an atom is

Answer 3

Protons and neutrons are situated in the atomic nucleus and electrons surround this nucleus.

Answer 4

Protons and neutrons are situated in the nucleus; electrons surround this nucleus.

Answer 5

Examples of involved forces: strong interaction, nuclear force, electromagnetic force.
