Periodic Trends

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

How does electronegativity change in the periodic table?

Back

Electronegativity generally increases across a period (left to right) and decreases down a group (top to bottom).

Front

Which element has a higher electronegativity: Fluorine (F) or Oxygen (O)?

Back

Fluorine (F) has a higher electronegativity than Oxygen (O).

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius generally decreases across a period and increases down a group.

Front

Which group of elements typically has the highest electronegativity?

Back

Group 17 (Halogens) typically has the highest electronegativity.

Front

What is the electronegativity of Carbon (C)?

Back

The electronegativity of Carbon (C) is approximately 2.5 on the Pauling scale.

Front

Which element has a larger atomic radius: Sodium (Na) or Potassium (K)?

Back

Potassium (K) has a larger atomic radius than Sodium (Na).

Front

What is the relationship between atomic size and electronegativity?

Back

As atomic size increases, electronegativity generally decreases due to the increased distance between the nucleus and the valence electrons.

Front

Which element is more electronegative: Chlorine (Cl) or Aluminum (Al)?

Back

Chlorine (Cl) is more electronegative than Aluminum (Al).

Front

What is the trend of ionization energy in the periodic table?

Back

Ionization energy generally increases across a period and decreases down a group.
