Periodic Table Trends Flashcard

Front

What happens to the atomic radius as you go from left to right within a period in the periodic table?

Back

It decreases.

Front

As you move down the periodic table, why do atoms get bigger?

Back

Because the atoms have more energy levels.

Front

Which element has the smallest ionization energy in Period 6?

Back

Cs (Cesium).

Front

If an electron is closer to the nucleus, how does this affect its removal and ionization energy?

Back

It will be harder to remove that electron and its ionization energy will be high.

Front

How does ionization energy change from left to right within a period in the periodic table?

Back

It increases.

Front

Define atomic radius.

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom in its gaseous state.

Front

Explain the trend of atomic radius as you move down a group in the periodic table.

Back

The atomic radius increases due to the addition of energy levels.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy generally decreases.

Front

What is the trend of electronegativity as you move across a period?

Back

Electronegativity increases from left to right.
