Question

If the same period, then look for the difference in bond energy and atomic radius size to determine.

A) Electronegativity
B) Ionization energy
C) Metallic character
D) Atomic mass

Answer 1

When looking at the same period on the periodic table, the differences in bond energy and atomic radius can be used to determine electronegativity, ionization energy, and metallic character.

Step-by-step explanation:

When looking at the same period on the periodic table, you can determine the difference in bond energy and atomic radius size to find the following:

• Electronegativity: Across a period, electronegativity increases as the atomic radius decreases. This means that atoms in the same period become more electronegative from left to right.
• Ionization energy: Across a period, ionization energy increases as the atomic radius decreases. This means that it becomes harder to remove an electron from an atom.
• Metallic character: Across a period, metallic character decreases as the atomic radius decreases. This means that elements in the same period become less metallic from left to right.
• Atomic mass: The atomic mass may vary across a period, but it is not directly related to bond energy or atomic radius size.
