To determine which of the given elements has the highest electron affinity, we can analyze the electron configurations and the stability of the resulting configurations after gaining an electron. Here’s a step-by-step breakdown of the solution:
What element has 13 electrons? What is the most reactive non-metallic atom? Which electrons are most responsible for the properties of an atom? What radioactive element has the lowest atomic number? What chemical element has the lowest boiling point?
Which group of elements has the lowest ionization energy? The elements of which group are nonreactive? What is the neutral atom that has its first two energy levels filled, has 2 electrons in its third energy level, and has no other electrons? What element is a metal...

aThe glucose oxidase enzyme is used as a biorecognition element: glucose oxidase oxidizes glucose to gluconic acid and shuffles electrons into the oxygen which is dissolved in the solution, and then reduced to hydrogen 葡糖氧化酶酵素使用作为biorecognition元素: 葡糖氧化酶氧化葡萄糖对葡糖酸并且拖曳...
Unpaired electrons can be considered as those electrons that alone can occupy the atomic orbitals. An atomic orbital has the capacity to contain two electrons but if it contains only one electron then that electron is called an unpaired electron....
