Trends in the Periodic Table

Front

What is electronegativity?

Back

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

Front

Which element in the periodic table has the highest electronegativity?

Back

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

Front

What is the term for the arrangement of elements in a particular form or combination?

Back

Configuration.

Front

What is a crystal lattice?

Back

A crystal lattice is the symmetrical three-dimensional arrangement of atoms inside a crystal.

Front

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

Back

Atoms get larger as you move down the periodic table due to the addition of energy levels.

Front

What is the reason atoms get larger down the periodic table?

Back

Atoms have more energy levels, which increases their size.

Front

What is electron shielding?

Back

Electron shielding is the phenomenon where inner shell electrons weaken the attraction between the nucleus and valence electrons.

Front

How does electron shielding affect the removal of valence electrons?

Back

Valence electrons are easier to remove when there are more inner shell electrons due to increased shielding.

Front

What is the trend in electronegativity across a period in the periodic table?

Back

Electronegativity generally increases across a period from left to right.

Front

What is the trend in atomic radius across a period in the periodic table?

Back

Atomic radius generally decreases across a period from left to right.
