Periodic Trends

Front

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

Back

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

Front

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

Back

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

Front

Define electronegativity.

Back

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

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.

Front

What is the trend for electronegativity as you move down a group?

Back

Electronegativity generally decreases as you move down a group.

Front

What is the trend for 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.

Front

What are alkali metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, known for being highly reactive.

Front

What are noble gases?

Back

Noble gases are the elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

Which group of elements has the smallest atomic radius?

Back

Noble gases have the smallest atomic radius.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases.
