Why arrange the elements in a table?

Seeing the chemical elements arranged in the modern periodic table is about as familiar as looking at a map of the world, but it wasn’t always so clear.

Dmitri Mendeleev, the creator of the periodic table, began collecting and sorting out the known properties of the elements in 1869, as if he were playing a game while traveling by train. He saw that there were groups of elements that exhibited similar properties, but he also saw that there were plenty of exceptions to the emerging pattern.

Incredibly, instead of giving up, they tried to change the measured property values to better fit the pattern! He also predicted that some elements should be present that were not at the time – again, in an attempt to work out patterns in his “game”.

There were many skeptics and it took many years to gain international acceptance, but once the newly discovered elements predicted Mendeleev’s, their patterns could not be ruled out. Furthermore, some of the properties that he “cheated” were later recalculated and found to be very close to his predictions.

Does the modern periodic table change? If yes, how and who does it?

The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (I-U-PAC).

While much of the periodic table is stable and unlikely to change, the IUPAC organization is responsible for deciding what needs to be changed. They have made criteria for the discovery of a new element.

Furthermore, any new element must be given a provisional name and symbol, and if valid, an official name. Such was the case when IUPAC recently reviewed elements 113, 115, 117 and 118, and decided to give them official names and symbols (bye, ununseptium and hello, Tennessine!).

Atomic weights found within a periodic table can be constant. The fact is that atomic weights have changed as a function of time. The IUPAC Commission on Isotopic Abundance and Atomic Weights (CIAAW) has been evaluating atomic weights and abundances since 1899. For example, in 1902 the atomic mass of carbon was 12.00 but today it is [12.0096, 12.0116]! Times have certainly changed as the source of the sample will determine the value.

Finally, the IUPAC assigns group names (lanthanoids and actinoids) and group numbering (1 to 18) and examines the membership of group 3 elements.

What is periodic table? Why is the periodic table made?

The periodic table is an arrangement of all the elements known to man according to increasing atomic number and recurring chemical properties. They are grouped in a tabular arrangement in which a row is a period and a column is a group.

Elements are arranged in the order of their increasing atomic number from left to right and top to bottom. thus,

Elements in the same group will have the same valence electron configuration and, therefore, have similar chemical properties.
Therefore, as the energy level of an atom increases, the number of energy sub-levels per energy level increases.

The first 94 elements of the periodic table are naturally occurring, while the remaining 95 to 118 have only been synthesized in laboratories or nuclear reactors.

  • The modern periodic table, which we use now, is a new and improved version of some of the models presented by scientists in the 19th and 20th centuries.
  • Dmitri Mendeleev put forth his periodic table based on the findings of some of the earlier scientists such as John Newlands and Antoine-Laurent de Lavoisier. However, Mendeleev is given sole credit for the development of the periodic table.

Why was Mendeleev’s periodic table widely accepted?

Dmitri Mendeleev, widely known as the father of the periodic table, came up with the first iteration of the periodic table as we use it now. Mendeleev’s periodic law differs from the modern periodic law in one main aspect.

Mendeleev modeled his periodic table on the basis of increasing atomic masses, whereas, the modern periodic law is based on increasing order of atomic numbers.

Even though Mendeleev’s periodic table was based on atomic mass, he was able to discover and predict the properties of some elements. During his time only about half of the elements we know now were known, and much of what was known about the elements was wrong. Mendeleev’s periodic table was published in 1869 in the German Journal of Chemistry.

Periodic table of Metals, Metalloids, and Nonmetals

Most metals are solid at room temperature, with a characteristic silvery luster (except for mercury, which is a liquid). Nonmetals are (generally) poor conductors of heat and electricity, and are not malleable or ductile; Many elemental nonmetals are gases at room temperature, while others are liquids and others are solids. Metalloids are intermediate in their properties. In their physical properties, they are more like nonmetals, but under certain conditions, many of them can be made to conduct electricity.

On many periodic tables, a jagged black line on the right side of the table (see picture below) separates metals from nonmetals. Metals are on the left of the line (except for hydrogen, which is a nonmetal), nonmetals are on the right of the line, and elements adjacent to the line are metalloids.
