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

Which element in Period 2 has the greatest atomic radius?

Back

Lithium (Li) has the greatest atomic radius in Period 2.

Front

What is ionization energy and how does it change across a period?

Back

Ionization energy is the energy required to remove an electron from an atom. It generally increases across a period from left to right.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.

Front

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

Back

Electronegativity decreases as you move down a group.

Front

Define ductility in terms of material properties.

Back

Ductility is the ability of a material to be drawn into a wire.

Front

Which halogen has the smallest atomic radius?

Back

Fluorine (F) has the smallest atomic radius among the halogens.

Front

What is effective nuclear charge and how does it affect atomic size?

Back

Effective nuclear charge is the net positive charge experienced by an electron in a multi-electron atom. It increases across a period, pulling electrons closer and reducing atomic size.

Front

How does the atomic radius change across a period from left to right?

Back

The atomic radius decreases as you move from left to right across a period due to increasing nuclear charge.

Front

What is the relationship between ionization energy and electronegativity?

Back

Generally, elements with high ionization energy also have high electronegativity.
