1.) The atomic radius of the elements in a group or family increase from the top to the bottom.
2.) The ionization energy decrease going down from the top to the bottom of the group.
3.) Electron affinity becomes less negative from the top to the bottom
4.) Element with high ionization energy has high electronegativity. Therefore, electronegativity decreases from top to the bottom of the group.
Periodic table tells us of the arrangement of elements and also the periodic properties of the elements as they are arranged in groups, periods and families.
some of the properties are :
1. Atomic radius
2. Ionization Energy
3. Electron Affinity
4. Electronegativity
5. Metallic character
6. e.tc
1.) The atomic radius of the elements in a group or family increase from the top to the bottom.
2.) The ionization energy decrease going down from the top to the bottom of the group.
3.) Electron affinity becomes less negative from the top to the bottom
4.) Element with high ionization energy has high electronegativity. Therefore, electronegativity decreases from top to the bottom of the group.
Due to the reason mention above, i can conclude the mystery elements are at the top of their families on the periodic table. An element that is in the same family as element C is likely to have all properties mentioned above.
