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 ...

Researchers have for the first time measured the first ionization energy of lawrencium, the last of the actinides, validating predictions of the element’s electronic structure (Nature 2015, DOI: ...

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 ...

The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...
