Using only the periodic table arrange the following elements in order of increas

Question

Using only the periodic table arrange the following elements in order of increasing ionization energy: boron, beryllium, oxygen, neon Lowest Highest Using only the periodic table arrange the following elements in order of increasing ionization energy: antimony, phosphorus, nitrogen, arsenic Lowest Highest Using only the periodic table arrange the following elements in order of increasing atomic radius carbon, boron, fluorine, beryllium Smallest Largest Using only the periodic table arrange the following elements in order of increasing atomic radius: arsenic, selenium, potassium, germanium Smallest Largest PIC COLLAGE

Explanation / Answer

In the modern periodic table , the ionisation energy decreases down the group (as the atomic size incraese) , and Increases along the period from left to right ( as the atomic size decreases).

So here , from lowest to highest :

1)

Lowest :Berrylium

Boron

Oxygen

Highest :Neon

2) lowest : Antimony

Arsenic

Phosphorus

Highest : Nitrogen

3)

Smallest : fluorine

carbon

boron

largest :berrylium

4)

smallest :selenium

arsenic

germanium

largest : potassium
