Unit 05 Review - PTable - 4 Periodic Properties - 532

Front

What happens to atomic radius across a period from left to right?

Back

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

Front

Which element has the largest atomic radius?

Back

Rubidium (Rb) has the largest atomic radius among O, Li, Rb, and Xe.

Front

Why do we measure atomic radius in bonded atoms?

Back

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

Front

What is the trend of periodic properties in d-block elements?

Back

The periodic properties of d-block elements have more exceptions and less regular trends.

Front

Which group of elements has the lowest ionization energies?

Back

Alkali metals have the lowest ionization energies.

Front

Define atomic radius.

Back

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

Front

What is ionization energy?

Back

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

Front

How does atomic radius change down a group?

Back

Atomic radius increases down a group due to the addition of energy levels.

Front

What is the relationship between nuclear charge and atomic radius?

Back

As nuclear charge increases, atomic radius decreases because electrons are pulled closer to the nucleus.

Front

What are noble gases known for in terms of reactivity?

Back

Noble gases are known for being largely unreactive due to their full valence electron shells.
