Because ions are only form by transfer of electrons and for this one one atom must have low ionization energy and other high electron affinity or their electronegativities difference is higher than 1.7.
Sr has a relatively low electron affinity. Electron affinity is the energy change when an atom gains an electron to form a negative ion, and for strontium, this energy change is lower compared to other elements.
To create an electron affinity reactor you will have to use the second ionization energy.
ok, so electron affinity is the amount of energy given off when a particular atom excepts electrons. Essentially, it is the likelihood that an atom will accept an electron, while ionization energy is how much energy is needed to take an electron off of a particular atom
Electron affinity is related to the formation of anions; electronegativity is related to the formation of cations.
An ionic bond forms when there is a large difference in electron affinity between two atoms. Typically, one atom has a high electron affinity (strongly attracts electrons) and the other atom has a low electron affinity (weakly attracts electrons), leading to the transfer of electrons from one atom to the other to form charged ions that are held together by electrostatic forces.
Chlorine has a high electron affinity due to its tendency to gain an electron to achieve a stable electron configuration. It also has a relatively low ionization energy, meaning it takes less energy to remove an electron from a chlorine atom compared to other elements.
The amount of energy required to remove an electron form an at is the ionization energy.
The ionization energy of a monoanion (e.g., Cl^-) is the energy required to remove an electron from the monoanion to form a neutral atom. The electron affinity of the neutral atom (e.g., Cl) is the energy released when an electron is added to form a negative ion (e.g., Cl^-). In general, the ionization energy and electron affinity are related as they both involve the interaction of electrons with atoms, but they are opposite processes in terms of energy change.
Periodic trends affect how certain elements on the periodic table react with each other. For example, Ionization energy tend : metals want to give off electrons , non metals want to gain electrons. This trend is essentially which elements are likely to react together and how they would react together, which is essentially ion formation (gain or loss of electrons through a reaction).
Ionization energy is an expression linked to extraction of an electron.
Ionization energy would be similar.
