The electronic configuration for elements a and b are:
a: 1s^2 2s^2 2p^6 3s^1
b: 1s^2 2s^2 2p^6 3s^2 3p^6 3d^6 4s^2
deduce the position of each element in the periodic table.

Reaction rate depends on how many molecules are coming into contact with each other with enough energy to react. increasing the temperature of the reactants will increase -
