Question 1 Report

An element with the electron configuration of 1s 22s 22p 6 would have a combining power of
Answer Details
The electron configuration 1s22s22p6 belongs to the noble gas neon (Ne). Elements in the noble gas family have a full outer shell of electrons, which makes them stable and unreactive. Combining power, also known as valency, is a measure of how many chemical bonds an element can form with other atoms. Noble gases have a combining power of 0 because they already have a full outer shell of electrons and do not need to gain or lose any electrons to achieve stability. Therefore, the answer is 0.
