Question

Which element will be more reactive and why → the element whose atomic
number is 10 or the one whose atomic number is 11?

Answer 1

the element whose atomic no. is 11 be more reactive because it is not stable because it has to loose one electron to get stable its electronic configuration will be 2,8,1 so it will share one electron to get stable.
 in case of element whose atomic no. is 10 is already stable because itts shells are completed its electronic configuration is 2,8.
thats why element with atomic no. 11 is more reactive

Answer 2
