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 valence electrons are in the same outermost shell. WebJan 30, 2024 · Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons. chive facebook

WebNov 1, 2024 · Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. … WebMar 25, 2024 · Ionic radii decreases across a period. This is due to the fact that metal cations lose electrons, causing the overall radius of an ion to decrease. Non-metal cations gain electrons, causing the overall radius of an ion to decrease, but this happens in reverse (compare fluorine to oxygen and nitrogen, which one gains the most electrons).

WebWithin a group, atomic radius increases from top to bottom. This is a consequence of increased energy levels as one moves down a group. Increased energy levels equates to larger orbitals and therefore more room for electrons to travel. Across a period, atomic radius decreases from left to right. WebDec 8, 2013 · On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to …

Even though the size of the atomic nucleus increases with larger atomic numbers moving across a period, the ionic and atomic radius decreases. This is because the effective positive force of the nucleus also increases, drawing in the electrons more …

WebFeb 27, 2024 · Non-metals, especially oxygen and fluorine, are thus OXIDIZING species, that tend to gain electrons, and the resultant ion should be larger than the parent atom. To address the original question then (at last!), ionic radii should increase across the Period from our left to our right. In order to answer your question properly you should ...
