Unit 05 Review - PTable - 4 Periodic Properties - 532

Front

What is the largest element among O, Li, Rb, and Xe?

Back

Rb (Rubidium) is the largest element due to its position in the periodic table.

Front

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

Back

Atomic radius gets smaller because nuclear charge increases and pulls valence electrons closer.

Front

Why is atomic radius measured in bonded atoms rather than in single atoms?

Back

It's hard to measure the edge of an 'electron cloud'.

Front

What are properties that vary regularly in a period or group of the periodic table called?

Back

Periodic properties.

Front

Which property varies like a regular snowman?

Back

Atomic radius.

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus to the outermost shell of an electron.

Front

What trend is observed in ionization energy across a period?

Back

Ionization energy generally increases across a period.

Front

What is electronegativity?

Back

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

Front

How does electronegativity change down a group in the periodic table?

Back

Electronegativity generally decreases down a group.

Front

What is the relationship between atomic size and metallic character?

Back

As atomic size increases, metallic character increases.
