A chemical change is a change in which one or more kinds of substances are transformed into a new kind of substance or several new kinds of substances. In simpler words, in a chemical change...

Most of the things we see around are made of compounds, in which atoms of one element are combined with atoms of other elements. Although there are 112 elements known today, ...

An electron configuration of an atom is a particular distribution of electrons among available subshells. The notion of for a configuration lists the subshell symbols one after the other, wi...

Matter exists in three states: solid state, liquid state and gaseous state. Matter, however, can change from one state to the other by heating or cooling. For example, when a solid is heated...

The element nitrogen is crucial to life: it is a component of all proteins, which are involved in every biochemical process that occurs in every living organsism. Most of the nit...
