In our daily life, we come across many objects, the knowledge about which can be gained by one or more of our senses like sight, touch, hearing, taste and smelling. These objects possess mass, occupy space and may have different…
CHEMISTRY AS A DISCIPLINE The human mind has always been very curious to make investigations and know about various activities/phenomena occurring around it. This curiosity has led him to collect information through experiments and observations. The curious mind has also…
Orbitals of The Atom The region in space within which there is maximum possibility of finding an electron in an atom is called an ATOMIC ORBITAL. We have s, p, d, and f orbitals. Shapes of s and p orbitals…
Constituents of an Atom Atoms are made up of sub-particles. Protons, electrons and neutrons. Proton has a positive charge, electron has a negative charge, and neutron has no charge. Atomic number and mass number The atomic number of an element…
Naming of Binary Compounds Nomenclature: This is the system of naming chemical compounds. The system is called IUPAC (International Union of Pure and Applied Chemistry). The naming is determined by the constituent elements in the compound and the oxidation number,…
Atoms and Molecules Matter is made up of discrete particles. The main ones are atoms, molecules, and ions. An atom is the smallest part of an element which can take part in a chemical reaction. A molecule is the smallest…
The importance of separating a mixture into its constituents cannot be overemphasised since most substances are needed in their pure form. There are many standard separation techniques. Some of these separating techniques are filtration, centrifugation and decantation. Others include sieving,…
Compound A Compound is a substance which contains two or more elements chemically combined. A compound is formed as a result of a chemical change. Examples of compounds are Compound Constituent Elements Water Hydrogen, oxygen Sand silicon, oxygen Limestone calcium,…
Elements & Symbols An element is a substance which cannot be split into simpler units by ordinary chemical process. There are over one hundred known elements. SYMBOLS OF ELEMENTS There are three ways in which symbols of elements are derived.…
Matter is anything that has weight and occupies space. It exists in three states, namely: solid, liquid and gas. The fundamental difference between the three states of matter depends on the degree of movement of the particles they are made…
Definition of Laboratory A laboratory is a room or building equipped for scientific experimentation or research. It is a special facility where experiments are done and typically contains scientific equipment and apparatus. Laboratory Apparatus Laboratory apparatus refers to the various…
Chemistry As a Science Subject Science is an organised body of knowledge gathered through systematic experimentation and philosophical observations. Chemistry can be defined as a branch of science which deals with the study of the nature, structure, composition, properties and…
