Question

How are molecules organized

Answer 1

An atom consists of a positively-charged nucleus, consisting of various combinations of protons and neutrons, and negatively-charged electrons which move around the nucleus in distribution patterns called shells. In a neutral atom, the number of electrons is equal to the number of protons, but an ionized atom would have more or fewer electrons. Electrons are much less massive than protons or neutrons. 

(2) How are groups of atoms organized? 
Atoms bond together with other atoms to form molecules or can be part of a crystal lattice.
