The video explains atomic size, also known as atomic radius, and its significance in understanding atomic reactivity. It discusses periodic trends, noting that atomic size increases down the periodic table and from right to left. The video explains these trends by examining energy levels and the number of protons, using examples to illustrate how these factors affect atomic size. It emphasizes that energy levels are more significant than nucleus strength when comparing atomic sizes.
