Solution
The correct option is B Ba
Barium is more reactive than Calcium.
The valence electrons in Barium are further away from the positive nucleus and so are less strongly held in place.
This means that Barium is able to release these two electrons more easily than Calcium.
Hence Barium is more reactive.
Barium is more reactive than Calcium.
The valence electrons in Barium are further away from the positive nucleus and so are less strongly held in place.
