#protactinium
- It lies in 7th period having Z=91
The outer electronic configuration is 6d^17s^2
- d-block element(transition)
So it will form polar covalent bond (2)
#Francium
Outer electronic configuration 7s^1
It will form ionic bond (3)
Answer:
a rection will most likely occur if the colliding partilces have the proper orientation and energy. The reactions occur becasue the molecules collide. But not all the collisions result in a reaction. The collisions have to meet some requirements
