Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period. Element Groups Elements in a group...
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
elements are categorized into different groups and periods, which aids in the study of the compounds created by those elements. It is also possible to analyze the ionization energy, electromagnetism, electron affinity, and so on.
