Elementary Concepts
Characteristic properties of compounds:
- Elements in a compound are present in a definite proportion
Example- 2 atoms of hydrogen + 1 atom of oxygen becomes 1 molecule of compound-water.
- Compounds have a definite set of properties
Elements that comprise a compound do not retain their original properties.
For example, hydrogen (combustible and non-supportive of combustion) + oxygen (non-combustible and supportive of combustion) becomes water (non-combustible and non-supportive of combustion)
Valency is the number of hydrogen atoms that can combine with one atom of the element to form a compound.

Famous quotes containing the words elementary and/or concepts:
“If men as individuals surrender to the call of their elementary instincts, avoiding pain and seeking satisfaction only for their own selves, the result for them all taken together must be a state of insecurity, of fear, and of promiscuous misery.”
—Albert Einstein (1879–1955)
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (1893–1978)
