The Periodic Table was developed in 1869 and it revolutionised science. It's organised into groups and periods, and an element's position can tell us a great deal . To revise what you learned in Year 10 and year 11, have a go at this GCSE chemistry quiz
The vertical columns are called Groups and the horizontal lines, Periods. The members of a Group have the same outer electron configuration but different quantum numbers at that outermost level. Within the table a number of blocks are labeled in terms of the nature of the orbital occupied by ...

In the s-block and p-block of the periodic table, elements within the same period generally do not exhibit trends and similarities in properties (vertical trends down groups are more significant). However in the d-block, trends across periods become significant, and in the f-block elements sh...

Periods are the rows of the periodic table, groups are the columns. Every element has a unique combination of period and group, and a unique atomic number.Explanations (5) L Lydia Kim Text 4 Reading the Periodic Table The periodic table is a chart with all the known elements. We've all...
Periodic table Periodic table (wide) The blocks running horizontally are called rows or periods. Atomic number increases across periods. Columns running vertically are called families or groups. Elements in the same group or family have similar chemical properties. Category: Periodic table...
The periodic table was developed in the late 1800s by a Russian chemist named Dmitri Mendeleev. He was a scientist that also instructed students. In the development of a lesson on the different elements known as his time, he was contemplating a way to display the properties of th...
