Periodic Table of Elements
What is Periodic Table of Elements?
The Periodic Table of Elements is a tabular arrangement of chemical elements organized by their atomic number, electron configuration, and recurring chemical properties. The table is divided into rows called periods and columns called groups or families.
Who Discovered Periodic Table of Elements?
The Periodic Table of Elements was not discovered by a single person, but its development is credited to Dmitri Mendeleev, a Russian chemist, who arranged elements based on their properties in 1869.
Who Made the Modern Periodic Table?
In 1913, Henry Moseley introduced an updated version of the periodic table, commonly referred to as “The Modern Periodic Table.”
How is the Periodic Table Arranged?
The Periodic Table is arranged in order of increasing atomic number, with elements grouped together based on similar chemical properties and arranged into periods (rows) and groups (columns).
What is Atomic Number?
The number of protons that constitutes an element’s nucleus is called its Atomic Number (Z). e.g. Carbon contains 6 protons then, its atomic number must be 6 only.
Can two different elements have the same atomic number?
The number of neutrons in an atom from two different elements can be similar, but the number of protons will never be same. Each element has a specific number of protons, which corresponds to the number of atoms.
How To Calculate Atomic Mass?
The atomic mass can be calculated by adding the mass of protons and neutrons in an element.
What is a Group in Periodic Table?
The Column in the periodic table refers to the group of the periodic table. The elements of the same group have similar physical and chemical properties.
Periodic Table of Elements
The Periodic table of elements is a systematic arrangement of 118 known chemical elements. These chemical elements are organized in order of increasing atomic number. The horizontal rows from left to right are called periods while the vertical columns from top to bottom are called groups in a periodic table.
