Unit 2 - Periodic Table - Honors Chemistry Final Exam Review

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. It generally increases across a period and decreases down a group in the periodic table.

Front

Which element has the highest ionization energy: Sodium (Na), Magnesium (Mg), Aluminum (Al), or Phosphorus (P)?

Back

Phosphorus (P) has the highest ionization energy among these elements.

Front

What is the common oxidation state of alkaline earth metals?

Back

The common oxidation state of alkaline earth metals is +2, because they are likely to lose two electrons.

Front

How does the size of a metal atom relate to its reactivity?

Back

Larger metal atoms are more reactive because their valence electrons are farther away from the nucleus, making them easier to lose.

Front

What are nonmetals?

Back

Nonmetals are elements that typically lack the properties of metals. They are usually poor conductors of heat and electricity and can gain electrons easily.

Front

Which models represent the most reactive nonmetals?

Back

Models 1 and 3 represent the most reactive nonmetals.

Front

What is the trend in reactivity for nonmetals in the periodic table?

Back

Reactivity of nonmetals generally increases as you move up a group and decreases as you move across a period from left to right.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties, allowing predictions about element behavior.

Front

What is an oxidation state?

Back

An oxidation state is a measure of the degree of oxidation of an atom in a compound, indicating the number of electrons lost or gained.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy generally decreases because the outermost electrons are farther from the nucleus and experience less attraction.
