Periodic Trends Practice

Front

What happens to electronegativity as you move from left to right across a period in the periodic table?

Back

Electronegativity increases.

Front

Which element has a higher electronegativity value: Niobium, Tin, Cadmium, or Iodine?

Back

Iodine has a higher electronegativity value.

Front

Which element has a lower electronegativity value: Calcium or Barium?

Back

Barium has a lower electronegativity value.

Front

What happens to the size of an atom as you move from top to bottom down a group in the periodic table?

Back

The size of an atom increases.

Front

Order the following elements in increasing ionization energy: Neon, Lithium, Carbon.

Back

Lithium, Carbon, Neon.

Front

Define electronegativity.

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

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

Back

Ionization energy generally increases.

Front

What is the trend of atomic radius as you move down a group in the periodic table?

Back

Atomic radius increases as you move down a group.

Front

Explain why electronegativity increases across a period.

Back

Electronegativity increases across a period due to increasing nuclear charge, which attracts electrons more strongly.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy generally decreases.
