Periodic Table Trends

Front

What is Electron Affinity?

Back

The energy change that occurs when an electron is added to a neutral atom.

Front

What is Ionization Energy?

Back

The amount of energy required to remove an electron from a neutral atom.

Front

Describe the trend of Electronegativity in the periodic table.

Back

Electronegativity increases from left to right across a period and decreases down a group.

Front

Which element has lower ionization energy: Phosphorus or Nitrogen?

Back

Phosphorus has lower ionization energy than Nitrogen.

Front

Which element has smaller atomic radii: Lithium or Sodium?

Back

Lithium has smaller atomic radii than Sodium.

Front

What is the trend of Atomic Radii in the periodic table?

Back

Atomic radii decrease from left to right across a period and increase down a group.

Front

Define Electronegativity.

Back

The tendency of an atom to attract electrons in a chemical bond.

Front

What is the relationship between Atomic Radii and Ionization Energy?

Back

As atomic radii increase, ionization energy generally decreases.

Front

What is the significance of the Periodic Law?

Back

The properties of elements are periodic functions of their atomic numbers.

Front

How does the position of an element in the periodic table affect its reactivity?

Back

Elements in the same group have similar reactivity due to their similar valence electron configurations.
