... Atoms combine when the compound formed id more stable than the separate atoms. The only group that seldom forms compounds is the noble gases (group 18). This is true because compounds of these atoms are almost always less stable than the original atom. Atoms with a partially stable outer energy leve ...

key concepts in chemistry
... Chemistry is usually defined in terms of being about the nature, properties and structure of matter, or about the properties and interactions of different substances. Chemistry is about the ‘stuff’ around us and about how we can think about this stuff in scientific terms. ...

Solid
Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma). It is characterized by structural rigidity and resistance to changes of shape or volume. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire volume available to it like a gas does. The atoms in a solid are tightly bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary ice) or irregularly (an amorphous solid such as common window glass).The branch of physics that deals with solids is called solid-state physics, and is the main branch of condensed matter physics (which also includes liquids). Materials science is primarily concerned with the physical and chemical properties of solids. Solid-state chemistry is especially concerned with the synthesis of novel materials, as well as the science of identification and chemical composition.
