Which has the lower electron affinity germanium or selenium?
Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.
Is the electron affinity of germanium high or low?
The electron affinity of germanium is considered to be moderate. Germanium is a metalloid element with an electron affinity that falls between that of metals and nonmetals.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
What is the electron affinity of sulfur?
The electron affinity of sulfur is -200 kJ/mol.
What is the second electron affinity of chlorine?
Chlorine has a negative second electron affinity because it releases energy when gaining an additional electron. This makes it less likely to accept a second electron compared to its first electron affinity, which is positive.
Which element in Group 13 has the lowest electron affinity?
Aluminum has the lowest electron affinity in Group 13 because it is the most electropositive element in this group due to its position in the periodic table. Electropositive elements tend to have lower electron affinities.
What is the electronic configuration of francium?
The electron configuration of francium is [Rn]7s1.
What element has no electron affinity?
Helium has no electron affinity.
Which has the lower electron affinity germanium or selenium?
Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.
How many electron orbital shells does francium have?
Francium has seven electron shells; electrons per shell: 2, 8, 18, 32, 18, 8, 1.
What is an electron's electron affinity?
chloline
What element has the LOWEST Ionization Energy Electron Affinity and Electronegativity?
The element with the lowest ionization energy, electron affinity, and electronegativity is francium (Fr). Francium is an alkali metal located at the bottom of Group 1 in the periodic table, which gives it a very low tendency to attract electrons and hold onto its own. Its large atomic size and low effective nuclear charge contribute to these low values, making it the least electronegative element.
Is the electron affinity of germanium high or low?
The electron affinity of germanium is considered to be moderate. Germanium is a metalloid element with an electron affinity that falls between that of metals and nonmetals.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
Does high value of electron affinity for an atom means that it will gain electron easily?
Yes, that is part of the definition of electron affinity.
Definition of electron affinity?
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
What is the electron affinity of sulfur?
The electron affinity of sulfur is -200 kJ/mol.
