Periodic Trends

Front

What are periodic trends?

Back

Periodic trends refer to the patterns and variations in the properties of elements across different periods and groups in the periodic table, such as electronegativity, atomic radius, and ionization energy.

Front

What is electronegativity?

Back

Electronegativity is a measure of how well an atom can attract and hold onto electrons in a chemical bond.

Front

Which element has the highest electronegativity?

Back

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

Front

What is the trend of electronegativity across a period?

Back

Electronegativity increases from left to right across a period in the periodic table.

Front

What is the trend of electronegativity down a group?

Back

Electronegativity decreases as you move down a group in the periodic table.

Front

What is atomic radius?

Back

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

Front

What is the trend of atomic radius across a period?

Back

Atomic radius decreases from left to right across a period due to increased nuclear charge.

Front

What is the trend of atomic radius down a group?

Back

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

Front

What is ionization energy?

Back

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

Front

What is the trend of ionization energy across a period?

Back

Ionization energy increases from left to right across a period.
