Periodic Trends

Front

What is the trend in atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group due to the addition of electron shells.

Front

What is the trend in atomic radius as you move across a period from left to right?

Back

The atomic radius decreases as you move across a period from left to right due to increased nuclear charge pulling electrons closer.

Front

Define the shielding effect in atomic structure.

Back

The shielding effect is the phenomenon where inner electrons block the attraction between the nucleus and the valence electrons, reducing the effective nuclear charge felt by the valence electrons.

Front

Which element has the largest atomic radius in Period 4?

Back

Potassium (K) has the largest atomic radius in Period 4.

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

Which element has the highest electronegativity in the periodic table?

Back

Fluorine (F) has the highest electronegativity in the periodic table.

Front

How does the atomic radius of Strontium compare to that of Zinc?

Back

Strontium has a larger atomic radius than Zinc.

Front

What is the relationship between atomic radius and ionization energy?

Back

Generally, as atomic radius increases, ionization energy decreases because the outer electrons are further from the nucleus and are held less tightly.

Front

What is the trend in electronegativity as you move down a group in the periodic table?

Back

Electronegativity generally decreases as you move down a group due to increased distance between the nucleus and valence electrons.

Front

What is the trend in electronegativity as you move across a period from left to right?

Back

Electronegativity generally increases as you move across a period from left to right due to increased nuclear charge.
