WebNov 14, 2024 · Summary. The atomic radius is the size of the atom, typically measured by the distance from the nucleus of the atom to the electron clouds around the nucleus. Covalent radius can be calculated by measuring the distance between the two nucleus of two atoms in covalent compound. The metallic radius can also be calculated by … WebElectron Affinity Chemistry Questions with Solutions. Q-1: The process requires absorption of energy is. F→F –. Cl→Cl –. O – →O 2-. H→H –.

Explanation: Electron affinity is the energy change when an atom gains an electron, and it is not directly related to the size or radius of an atom. In fact, electron affinity generally ... WebThe electron affinity, E ea, of an atom or molecule is the energy required to detach an electron from a singly charged negative ion, i.e., the energy change for the process . X-→ X + e −. An equivalent definition is the energy released (E initial − E final) when an electron is attached to a neutral atom or molecule.It should be noted that the sign convention for …
The electron affinity (Eea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion. X(g) + e → X (g) + energy This is not the same as the enthalpy change of electron capture ionization, which is defined as negative when energy is released. In other words, the enthalpy change and the electron affinity … WebQuestion. Give detailed Solution with explanation needed.

Sodium, aluminum, phosphorus, and chlorine are all in the same row (period) of the periodic table. The electron affinity, a measure of the energy released when an atom gains an electron (an exothermic reaction), increases from left to right across the periodic table because when a smaller atom gains an electron, the force between the electron …
WebNov 26, 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Arsenic in the gas phase, for example, gives off energy when it gains an electron to form an ion of Arsenic. As + e – → As – – ∆H = Affinity = 78 kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity.
WebJan 30, 2024 · Electronegativity. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to cesium and francium which are the least electronegative at 0.7. clean derek minor lyricsWebOct 14, 2024 · ความสัมพันธ์ของอิเล็กตรอนเป็นตัววัดว่าอะตอมที่เป็นกลาง ... downtown big bear barsWebOct 11, 2024 · The electron affinity is defined as the energy change that occurs when an atom gains an electron, releasing energy in the process.
