Question

Two elements have atomic number 10 and 11 respectively. Which of the two would be more chemically reactive

Answer 1

Second element would be more reactive

Answer 2

The second element of atomic number is more reactive.
because the first element's electronic configuration is 2,8. so,it becomes stable amd does not react anymore.And also it becomes inert too.
the second element's electronic configuration is 2,8,1. so it is more reactive than the first element.
