Using only the periodic table arrange the following elements in order of increasing atomic radius:phosphorus, aluminum, magnesium, chlorinethenmagnesium, barium, strontium, calciumUsing only the periodic table arrange the following elements in order of increasing ionization energy:chlorine, phosphorus, argon, siliconand then carbon, germanium, tin, silicon

Sure, here are the answers:

1. Arranging the elements phosphorus, aluminum, magnesium, and chlorine in order of increasing atomic radius:

Atomic radius generally decreases as you move from left to right across a period (row) and increases as you move down a group (column) on the periodic table.

So, the order would be: Chlorine < Phosphorus < Aluminum < Magnesium

2. Arranging the elements magnesium, barium, strontium, and calcium in order of increasing atomic radius:

Again, atomic radius increases as you move down a group on the periodic table.

So, the order would be: Magnesium < Calcium < Strontium < Barium

3. Arranging the elements chlorine, phosphorus, argon, and silicon in order of increasing ionization energy:

Ionization energy generally increases as you move from left to right across a period and decreases as you move down a group on the periodic table.

So, the order would be: Silicon < Phosphorus < Chlorine < Argon

4. Arranging the elements carbon, germanium, tin, and silicon in order of increasing ionization energy:

Again, ionization energy increases as you move from left to right across a period and decreases as you move down a group.

So, the order would be: Tin < Germanium < Silicon < Carbon
