The periodic table isn’t just a list of elements—it’s a map of predictable patterns called periodic trends. These trends, like atomic radius, electronegativity, and ionization energy, help scientists ...
The United Nations have proclaimed 2019 to be the International Year of the Periodic Table of Chemical Elements (IYPT 2019) to mark the 150th anniversary of the classification system that decorates ...
In their momentary life span, atoms of lawrencium, element 103, may have left a lasting impression on the structure of the periodic table. For the first time, researchers have measured a basic ...
This illustration shows a typewriter with the keys depicted as the periodic table. Hands are typing on it, and the sheet of paper coming out of it shows the words "Tales from the table." Credit: Chris ...
New Scientist: A new version of the periodic table could change how we measure time
A new version of the periodic table of elements has predicted hundreds of highly charged ions that could be used to create the next generation of optical atomic clocks. The periodic table, first ...
A new version of the periodic table could change how we measure time
Students learn to describe the pattern in atomic number, atomic mass and atomic radius. Trends on the Periodic Table: Students learn to describe the pattern in atomic number, atomic mass, atomic ...
This lesson utilizes an adaptation of the board game Periodic: A Game of the Elements to help students better understand both general periodic trends and the law of conservation of energy. This ...
David Cole-Hamilton – previously president of EuChemS – explains why we need to be mindful of many of the elements as a limited resource. The periodic table allows us to understand chemistry at a ...
