Periodic Table & Trends

Front

What do elements in the same column of the periodic table have in common?

Back

They have the same number of Valence Electrons.

Front

What happens to atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases because you add more and more shells (energy levels).

Front

How does electronegativity change as you move down group 16 in the periodic table?

Back

Electronegativity decreases.

Front

Which element has a lower ionization energy than Scandium (Sc)?

Back

Calcium (Ca) has a lower ionization energy than Scandium.

Front

Which element has the highest electronegativity among W, X, Y, and Z?

Back

Element W has the highest electronegativity.

Front

What is the definition of ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What trend is observed in ionization energy as you move across a period from left to right?

Back

Ionization energy generally increases as you move from left to right across a period.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy decreases.

Front

What are valence electrons?

Back

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

Front

What is the significance of the periodic table's groups?

Back

Elements in the same group have similar chemical properties due to having the same number of valence electrons.
