Meyer did contribute to the development of the periodic table in another way though. He was the first person to recognise the periodic trends in the properties of elements, and the graph shows the ...

The covalent radius (a measure of how large individual atoms are) shows different trends if you are moving ... As you move from left to right across the periodic table, atoms have more electrons ...

The rows of the table are called periods, and the columns are called groups. Elements from the same column group of the periodic table show similar chemical characteristics. Trends run through the ...

Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in ...

Researchers from the University of Liverpool are part of an international collaboration that has made significant advances in ...

The periodic table arranges all the chemical elements in a specific way. Patterns are visible in the way that elements behave, and this allows us to make predictions about other elements.

In this activity, students will use the online periodic table, ptable.com, to investigate a number of chemistry concepts. Students will use this online resource to explore information about the ...

Using lasers beams to measure the nuclear radius of isotopes at the end of periodic table. Elements at the end of the ...
