Periodic Trends Flashcard

Front

What is the atomic radius trend in Group 18 elements?

Back

The atomic radius increases down the group due to the addition of electron shells.

Front

Define Coulombic Attraction in the context of atomic structure.

Back

Coulombic Attraction refers to the electrostatic force of attraction between positively charged protons in the nucleus and negatively charged electrons.

Front

What is Ionization Energy?

Back

Ionization Energy is the energy required to remove an electron from an atom in its gaseous state.

Front

Which element has a higher ionization energy: Aluminum (Al) or Chlorine (Cl)?

Back

Chlorine (Cl) has a higher ionization energy than Aluminum (Al).

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 atomic radius change across a period?

Back

The atomic radius decreases across a period from left to right due to increasing nuclear charge.

Front

What is the trend of ionization energy down a group?

Back

Ionization energy generally decreases down a group due to increased distance of the outer electrons from the nucleus.

Front

Explain the relationship between atomic radius and ionization energy.

Back

As atomic radius increases, ionization energy decreases because the outer electrons are further from the nucleus and experience less attraction.

Front

What is the significance of the noble gases in periodic trends?

Back

Noble gases have complete valence shells, making them stable and generally unreactive, which affects trends in electronegativity and ionization energy.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity of all elements.
