Learn how elements are grouped in the periodic table Learn how elements are grouped in the periodic table Determining the group or period in which an element belongs to may be tricky at first but with time of practice, it will look very easy and simple. When I was thought this topic back then in school, I found it very difficult understanding it but I kept on practicing until I became a genius in this aspect of chemistry. You might want to know what I discovered while practicing and how I became good in this… this article has unveiled the hidden fact to grouping the most known elements (first twenty elements) using their electronic configuration and that’s why you should read this carefully to the end and follow each steps practically. You don’t wanna spend more time, right? Why don’t you pick up a piece of jotter and a pen. • For you to determine the group or period in which an element belongs to, you should know the element, its symbol, and most especially its atomic number a

Respiration characterizes a living organism (human or animal) - there is no live without respiration. We live immersed in gases since the earth is filled with gases. Among all gases in the atmosphere, oxygen gas is inhaled for cellular respiration in animal while plants breath utilizes carbon IV oxide for their usage during respiration. Cellular respiration is the step-by-step process involved in the oxidation of sugars to produce energy. In the ecological system, green plants are the main source of food and energy to animals and some other plants (non-green plants). They manufacture their food by a process called photosynthesis by utilizing energy from external source (the sun). When the food products from these plants are consumed, the essential nutrients are obtained during digestion. The carbohydrate is digested into soluble glucose molecule which then assimilates into the blood stream and is therefore transported into the cells. This is the point where cellular respiration b
