How can we find reactivity using the periodic table?
Answers
Answer:
Periodic table ensures you the exact atomic number of an element you sort of it. You have to find out the element's electronic configuration. Then the element has only three choices because it has the probability of being:
1. Inert element (or)
2. Cation forming element (or)
3. Anion forming element.
Cations are positively charged and anions are negatively charged. If the last orbital that the chosen element has number less than 4, it forms cation but if it outstrips 4, it forms anion. Reactivity depends on the number of electrons present in the final orbital. If there are more than 3 electrons and less than 6 electrons in the electronic configurations of elements, they are not ferociously reactive. However there are few exceptions. Down to the group in left hand side of the periodic table, reactivity intensifies but down to the group of p-block elements rectivity decreases.
