Chemistry Basics Quiz

Chemistry is the scientific study of the properties and behavior of matter.

Chemistry studies the chemical elements that make up matter and compounds made of atoms, molecules, and ions.

Chemistry provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.

<p>A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. It involves changes in the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei. The initial substances involved are called reactants or reagents, and the resulting substances are called products. Chemical reactions are usually characterized by a chemical change, and they occur at a characteristic reaction rate at a given temperature and chemical concentration.</p> Signup and view all the answers

<p>Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. This differs from classical chemical reactions as it involves changes to the nuclei of the elements present, in addition to changes in the positions of electrons.</p> Signup and view all the answers
