Classification of Elements and Periodicity

Understanding the difference between Period and Group In the periodic table, when you move from left to right, it’s called moving across a period. When you move from top to bottom, it’s called moving within a Group. So, a row(horizontal) is known as a Period while a column(vertical) is termed as a Group. Periodic trends […]

Dmitri Mendeleev, a Russian chemist who formulated the periodic law as a link between chemical properties and atomic mass, drew the first well recognised periodic chart in 1869. Because not all elements were known at the time, Mendeleev’s periodic table included gaps, but he was able to predict qualities of some of the missing elements

Open Intervals and closed intervals are used in mathematics to describe data ranges. Interval symbols and number patterns may be used to help students grasp the distinction between an open interval and a closed interval and the many other forms of intervals. An open or closed interval can represent numeric values. In case you are

Considering the large number of new elements that were found during the eighteenth and nineteenth centuries, the broad classification of elements into metals and non-metals proved ineffective. There were a number of studies carried out in order to find pieces that shared similar characteristics and group them together. What are Dobereiner’s Triads, and how do

What is a Diagonal Relationship in the Periodic Table? According to their position, some elements in the periodic table connect on an adjacent basis. The modern periodic table has the positioning criteria according to the element’s atomic number. The second and third row of the periodic table has the placement of elements with diagonal relationships.

An element’s chemical properties are closely associated with the atoms in terms of size. A diagonal relationship exists between specific pairings of diagonally adjacent nodes in the second and third periods of the atomic numbers. These pairings share several common features. For example, in the periodic table of elements, the diagonal relationship of lithium and magnesium is

The elements in Group 1 of the periodic table are arranged in a vertical column, mainly on the left side. Group 1 elements are referred to as alkali metals. Each alkali metal atom’s outermost surface contains a single electron with a significantly weaker bond to the nucleus than electrons in the inner shells. Additionally, alkali

Average refers to the mean value of the values, which we can also understand as the sum divided by the total number of values in a particular set. It is one of the most commonly used measures of central tendency employed to make a statistical summary of enormous data. A simple example of the average

The elements are arranged in such a manner in the periodic table that every element with similar chemical and physical properties will be placed together in columns known as groups. Based on this, several properties can be defined, like atomic radius, ionization enthalpy, stability, electron gain enthalpy, and so on. Even though the properties follow

The term allotropy comes from the Ancient Greek word where ‘allos’ means ‘other’ and ‘tropos’ represents ‘manner or form’. It refers to the property of chemical elements to exist in variable to different forms in a similar physical state. Allotropes refer to different structural changes in an element i.e. the atoms of an element are
