Chemical Combinations are very important in Chemistry because it aids in bringing stability to atoms of some elements especially those whose outer shells are incomplete. Atoms of elements like Neon, Helium, and Argon are completely filled with electrons as depicted in the image below while atoms of other elements are unstable but
The Periodic table represents a simple systematic way of classifying elements. A Russian Scientist Mendeleev 1869 formulated the periodic law based on the relative atomic mass of the elements however, the modern version which is currently in use today is based on their atomic numbers and it was suggested by Moseley in
The electrons in an atom are in continuous and constant motion in shells around the nucleus, represented by capital letters K,L, M,N, etc. The K shell is the innermost and the nearest to the nucleus followed by the L-shell, then the M-shell the N-shell etc. Each shell is at the energy level
Introduction To Isotophes In Chemistry[ISOTOPHY& FINDING RELATIVE ATOMIC MASS OF ISOTOPHIC ELEMENTS]
You must have heard of Isotophes before in Chemistry but only a few do not know what it means. Scientific discoveries have shown that there are atoms of the same element with different masses. This is contrary to one of Dalton’s postulates and the phenomenon is known as isotopes. Isotophy is the
This is one of the foundational topic in Chemistry that one must take proper note of in order to understand other topics in Chemistry. As a beginner in Chemistry, you must acquaint yourself with this topic. Now, the Greek philosopher named Democritus(400 B.C) was the first to show that matter is made
You might have been in a dilemma where you have to separate things like water and oil and some even wonder if its possible. Separation techniques are physical methods used for separating the constituents of various mixtures. The principle of separation is based on the physical properties of the constituents of the
