Unit 4: Periodic Trends and Electron Configurations Review

Front

What is a transition metal?

Back

Transition metals are elements found in groups 3 to 12 of the periodic table, characterized by their ability to form variable oxidation states and colored compounds. Example: Iron (Fe) is a transition metal.

Front

What is the trend for ionization energy across a period in the periodic table?

Back

Ionization energy generally increases from left to right across a period due to increasing nuclear charge, which holds electrons more tightly.

Front

Which element has the highest electronegativity?

Back

Fluorine is the element with the highest electronegativity, meaning it has a strong tendency to attract electrons in a chemical bond.

Front

What is the electron configuration of Carbon?

Back

Front

What is a halogen?

Back

Halogens are elements found in group 17 of the periodic table, known for their reactivity and tendency to form salts with metals. Example: Chlorine (Cl) is a halogen.

Front

What is the general trend for atomic radius across a period?

Back

Atomic radius generally decreases from left to right across a period due to increased nuclear charge pulling electrons closer to the nucleus.

Front

What is the general trend for electronegativity across a period?

Back

Electronegativity generally increases from left to right across a period as atoms become more effective at attracting electrons.

Front

What is the electron configuration of Oxygen?

Back

Front

What are noble gases?

Back

Noble gases are elements in group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell. Example: Neon (Ne) is a noble gas.

Front

What is the trend for metallic character across a period?

Back

Metallic character generally decreases from left to right across a period as elements become less likely to lose electrons.
