Periodic Table Trends

Front

What is ionization energy?

Back

Ionization energy is the amount of energy required to remove an electron from an atom.

Front

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

Back

Atoms tend to get smaller as you move across the periodic table because the atoms have more protons.

Front

Which element has similar chemical properties to oxygen and selenium, has an atomic number greater than krypton but less than iodine?

Back

The element is tellurium.

Front

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

Back

Atoms get bigger as you move down the periodic table because the atoms have more energy levels.

Front

Which type of element has the largest atomic radius?

Back

Metals have the largest atomic radius.

Front

Define electronegativity.

Back

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

Front

How does electronegativity change across a period?

Back

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

Front

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

Back

Electronegativity generally decreases as you move down a group in the periodic table.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases.

Front

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

Back

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