groups in science

In science, a "group" refers to a category that organizes similar items based on shared characteristics. For example, in chemistry, elements are grouped in the periodic table based on their properties, such as reactivity or atomic structure. In biology, organisms are grouped into categories like species and families that share genetic traits. Groups help scientists understand relationships, predict behavior, and organize knowledge efficiently. Essentially, groups are a way to classify and make sense of complex information by arranging items with common features together.
