Q: Arrange the element according to the increase radius or size 1. Na, K, Cs Fr, Rb
2.  Ca, Sr, Ba, Ra, Mg

Refer to the periodic table to do this.

Explanation:

1. Na, K, Cs Fr, Rb

  Sodium, Potassium, Cesium, Francium, Rubidium

  3, 4, 6, 7, 5

Ascending order: Na, K, Rb, Cs, Fr

2. Ca, Sr, Ba, Ra, Mg

   Calcium, Strontium, Barium, Radium, Magnesium

   4, 5, 6, 7, 3

Ascending Order: Mg, Ca, Sr, Ba, Ra

When doing the electronic configuration of the elements, count how many number of divides it has. For example, Na(Sodium) has 11 electrons and it is divided like this: 2,8,1. So it divides into 3 parts so there will 3 shells for sodium.

Hopefully this helps!!

it should be all of them because it asks if you included all of those in your answer
