Explain the atomic radius trend
WebWhat causes this trend? Answer: The smaller the atomic radius in an element, the more ionization energy it will have. So when you go across the periodic table, the IE will decrease.

Explain the atomic radius trend
Did you know?
WebAtomic Radius is a term describing the distance between an atom’s nucleus, and its outermost electron shell. Several factors affect this distance; including the number of an element, and the number of electron shells. Through Periodic trends, the atomic radius increases in size further left of a period, and lower down a group. WebApr 7, 2024 · The trend in atomic radius across the periodic table also varies from the trend in ionic radius. The atomic radius decreases from left to right across a period because the number of shells remains constant, but the protonic charge keeps increasing, causing a greater attractive pull on the outermost shell electrons. The ionic radius trend …
WebAn atomic radius is half the distance between adjacent atoms of the same element in a molecule. Measuring the atomic radii of chemical elements is a complicated task as the size of an atom is of the order of 1.2×10-10 m. The electron cloud forming the shell of an … WebThe atomic radius is the distance from the atomic nucleus to the outermost electron orbital in an atom.In general, the atomic radius decreases as we move from left to right in a period, and it increases when we go down a group. This is because in periods, the …
WebTrends in reactivity in the periodic table Resource RSC Education This could be used to follow up some work on the periodic table where the trends in reactivity in groups 1 and 7 have been identified. It can be used as a differentiated activity for … WebYou know the maximum capacity of p orbital is 6 electrons. so N has three 2p electrons and O has four 2p electrons. This case is kind of exception. Since Nitrogen is half filled coz it has 3 electrons out of 6 electrons that can be occupied in p orbital it has higher ionization energy compared to that of oxygen.
