Electron affinity across the period
WebAug 31, 2024 · Electron affinity also applies to molecules, in some cases. Electron affinity is the energy change when an atom gains an electron. For most elements, except noble gases, this is an exothermic process. Electron affinity increases moving across a period and sometimes decreases moving down a group. WebExplain whether they matched the predicted periodic trends. Include: --The atomic radii decreased across Period 3 and increased down Group 17. --The ionic radii decreased across a period for the positive sodium and magnesium ions, increased for phosphorus, and then decreased again. --The electron affinity and electronegativity increased …

Web0. Well the electronegativity increases across the period because the electrons are being added onto the same energy level,this increases the number of electrons of an atom,the increase of electrons of an atom also leads to increase in clear charge,in fact the nuclear charge increases more,this leads to attraction of electrons by the nuclear ...

Negative sign meaning energy released (exothermic) Trends Increases across a …
WebMay 10, 2024 · Electron affinity generally increases across a period in the periodic table and sometimes decreases down a group. The chemical rationale for changes in electron affinity across the periodic table is the increased effective nuclear charge across a period and up a group. WebChemists define electron affinity as the change in energy, measured in units of kJ/mole, experienced when an electron is added to a gaseous atom. This process creates a negative ion. This process differs from …
WebJul 3, 2024 · Ionization, together with atomic and ionic radius, electronegativity, electron affinity, and metallicity, follows a trend on the periodic table of elements. ... This is because the atomic radius generally decreases moving across a period, so there is a greater effective attraction between the negatively charged electrons and positively …
