Ionic bonds are formed as a result of a redox reaction.
<em>Formation of cations:</em> In which atoms of an element (metal) with low ionization energy give some electrons to reach stable electronic configuration.
<em>Formation of anions:</em> in which atoms of another element with high electron affinity accepts electrons to achieve a stable electronic configuration.
<em>Example: NaCl</em>, the sodium atoms loss electron forming Na⁺ and the chlorine atoms gain electron forming Cl⁻, then the ions are attracted to each other with 1:1 ration forming the ionic compound NaCl.
Na + Cl → Na⁺ + Cl⁻ → NaCl
<u><em>What is the attractive force within the ionic bond?</em></u>
The attractive force within the ionic bond is the electrostatic attraction between the positively charged ions (cations, Na⁺) and the negatively charged ions (anions, Cl⁻).
During a beta decay, one neutron convert into one proton and one electron. The proton remained in nucleus while electron move away known as beta radiation. So atomic mass will be remained same but atomic no will increase by one. So correct ans will be with 218, 86 Po and beta radiation.
