Chemistry has never been very successful in attracting students. Most of the time it has been branded as a very bland and boring subject to read. We believe that this is because of the myths that develop inside various students while studying Chemistry. They often think that Chemistry is a subject which is only about memorizing the various complicated laws and principles. But Chemistry is beyond that. In our dynamic classes of A level chemistry tuition, O level chemistry tuition, JC chemistry tuition for the students of Singapore, our teachers will show you how impressive Chemistry can be and will guide you to success.
The periodic table is regarded as the most important aspect of chemistry. Russian chemist Dmitri Mendeleev published the first recognizable periodic table in 1869. From the very beginning, the table is explained for the students to understand the concepts better. Special chemistry tuition is conducted to give a clearer understanding of the module. The periodic table is a tabular display of chemical elements arranged based on the atomic number, electron configuration, and chemical properties. There are seven rows in the table, termed as periods. Periods have metals on the left and non-metals on the right. Also known as the periodic table of elements, the organization is such that it is easy for any layman who has basic knowledge of chemistry to understand the unique properties of individual elements. The periodic table of elements includes names, atomic number, symbol and mass. It is color-coded for easier reference by students and researchers. Each row and column have specific characteristics. Each element is placed in its specific location due to its atomic structure.
The number of protons and electrons in the element are indicated by the atomic number. The letters in each block represent the atomic symbol. Group numbers are placed above the periodic table. Elements in the same group have the same number of electrons which shows that they have similar properties. Periodic numbers are the numbers placed beside the periodic table. Atomic radius tends to decrease as we move left across a period. This happens because each successive element has an added electron and proton. It is to be noted that while moving from left to right across a period, the more we escalate towards the right, the more energy is required to remove an electron because they become more tightly bound. The periodic table explains the number of protons, neutrons, and electrons, the mass, atomic number, mass number, valence electrons, etc.
