Periodic Trends and Classification

Front

What is ionization energy?

Back

Ionization energy is the amount of energy required to remove an electron from an atom.

Front

What happens to atomic size as you move down the periodic table?

Back

As you move down the periodic table, atoms get larger because they have more energy levels.

Front

What is the correct order of atomic radii for oxygen, fluorine, and nitrogen?

Back

The correct order of atomic radii is F < O < N.

Front

Which atom has the largest atomic radius?

Back

Francium has the largest atomic radius.

Front

What trend is observed in ionization energy as you move across a period from left to right?

Back

Ionization energy generally increases as you move from left to right across a period.

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 in the periodic table.

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

How does the number of protons affect ionization energy?

Back

As the number of protons increases, ionization energy generally increases due to greater nuclear charge.

Front

What is the relationship between atomic size and metallic character?

Back

As atomic size increases, metallic character generally increases.

Front

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

Back

Ionization energy generally decreases as you move down a group in the periodic table.
