The significance of boron electron affinity in chemical bonding and reactivity lies in its ability to attract and bond with other atoms to form stable compounds. Boron's electron affinity affects its reactivity and ability to form bonds with other elements, influencing the types of compounds it can form and its overall chemical behavior.
Bromine (Br) has a more negative electron affinity than boron (B). This means that bromine has a higher tendency to accept an electron to form a negative ion.
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.
The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.
Boron has one unpaired electron.

chloline
Boron has one unpaired electron.
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.
Yes, that is part of the 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
The electron affinity of sulfur is -200 kJ/mol.
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.
