EVERYDAY SCIENCE

Detailed explanation-1: -Chemistry is the study of substances-that is, elements and compounds-while biology is the study of living things.

Detailed explanation-2: -Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds.

Detailed explanation-3: -Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.

Detailed explanation-4: -Answer and Explanation: The chemical properties of an element are determined by the electron configuration of the element, especially the valence shell electron configuration. The valence shell is the outermost energy level or shell being populated as one moves from left to right on the Periodic Table of the Elements.
