PERIODIC TRENDS (F.A.) End of Class

Front

What are Transition Metals?

Back

Transition Metals are elements found in groups 3-12 of the periodic table, characterized by their ability to form variable oxidation states and colored compounds.

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

Why does atomic radius decrease as you move from left to right across a period?

Back

Atomic radius decreases because the number of protons increases, leading to a stronger attraction between the nucleus and the electrons.

Front

What is the trend of atomic size across a period?

Back

Atoms tend to get smaller as you move across a period due to an increase in the number of protons.

Front

What is electronegativity?

Back

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

Front

How does electronegativity change across a period?

Back

Electronegativity increases from left to right within a period.

Front

How does electronegativity change down a group?

Back

Electronegativity decreases from top to bottom within a group.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases because the outer electrons are further from the nucleus and are less tightly held.

Front

What are the characteristics of metals in the periodic table?

Back

Metals are typically shiny, good conductors of heat and electricity, malleable, and ductile.

Front

What are the characteristics of nonmetals in the periodic table?

Back

Nonmetals are typically dull, poor conductors of heat and electricity, and brittle in solid form.
