Periodic Table & Trends

Front

What is the arrangement of the Modern Periodic Table of Elements based on?

Back

Atomic number.

Front

Which element has a larger atomic radius than Zinc?

Back

Strontium.

Front

Why does Francium (Fr) have the lowest ionization energy in Group 1?

Back

Its 1 valence electron is very far from the nucleus, so little energy is needed to remove it.

Front

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

Back

Atoms tend to get smaller because the atoms have more protons.

Front

Which group of the periodic table is composed of inert (not reactive) gases?

Back

Noble gases.

Front

What is the significance of atomic number in the periodic table?

Back

It determines the position of an element in the periodic table and its chemical properties.

Front

What trend is observed in ionization energy as you move across a period?

Back

Ionization energy generally increases.

Front

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

Back

Electronegativity generally decreases.

Front

What are alkali metals and where are they located in the periodic table?

Back

Alkali metals are located in Group 1 and are highly reactive.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy decreases.
