Periodic Table & Trends

Front

What is the Modern Periodic Table of Elements arranged by?

Back

Atomic number.

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

Which element has a larger atomic radius than Zinc?

Back

Strontium.

Front

What are the vertical columns in the Periodic Table called?

Back

Groups.

Front

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

Back

Atoms tend to get smaller because they have more protons.

Front

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

Back

It determines the element's position and properties.

Front

What trend is observed in ionization energy as you move down a group in the periodic table?

Back

Ionization energy decreases.

Front

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

Back

Electronegativity increases.

Front

Define 'valence electrons'.

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy decreases.
