Periodic Table

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, with concepts like the periodic table of elements periods offering deeper insights into the subject.

Why Is the Periodic Table Important?

 

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.

 

Understanding the Periodic Table of Elements

 

Special chemistry tuition is conducted to give a clearer understanding of the module. The periodic table is a tabular display of chemical elements . It arranged based on the atomic number, electron configuration, and chemical properties.

 

What Are Periods in the Periodic Table?

 

There are seven rows in the table, termed as periods. Periods have metals on the left and non-metals on the right.

 

Features of the Periodic Table

 

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.

 

How Elements Are Grouped

 

Each row and column have specific characteristics. Each element is placed in its specific location due to its atomic structure.

 

Understanding Atomic Numbers and Symbols

 

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.

 

Why Period Numbers Matter

 

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.

 

Trends in 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.

 

Learn Chemistry with Clarity

 

The periodic table explains the number of protons, neutrons, and electrons, the mass, atomic number, mass number, valence electrons, etc.

 

FAQs

 

Q1: What is the periodic table?

The periodic table is a chart that organizes all known elements based on their properties. It helps students understand how elements are related to each other.

 

Q2: How is the periodic table used in O Level chemistry?

In O Level chemistry, the periodic table is used to learn about elements, their groups, periods, and how they react with each other.

 

 

Q3: What is the role of the periodic table in A Level chemistry?

In A Level chemistry, the periodic table helps students understand more advanced concepts like trends in atomic size, electronegativity, and reactivity.

 

 

Q4: How do I study the periodic table for O Level exams?

To study the periodic table for O Level, focus on learning the groups, periods, and the key properties of different elements.

 

 

Q5: Why is the periodic table important in secondary school chemistry?

The periodic table is crucial in secondary school chemistry as it helps students understand the structure and behavior of elements, making it easier to learn chemistry concepts.

 

Q6: Can tuition help me understand the periodic table better?

Yes, chemistry tuition can provide clear explanations and examples of the periodic table. It makes easier to grasp the concepts for both O Level and A Level students.
