Unit 4

Front

What are inner transition elements?

Back

Inner transition elements are the elements found in the f-block of the periodic table, which include the lanthanides and actinides. They are characterized by the filling of f-orbitals.

Front

Which element has a greater ionization energy: Magnesium or Phosphorus?

Back

Phosphorus has a greater ionization energy than Magnesium due to its higher effective nuclear charge and smaller atomic radius.

Front

What group of the periodic table is composed of inert gases?

Back

The noble gases are the group of the periodic table that consists of inert gases, known for their lack of reactivity due to having a full valence shell.

Front

What do elements in the same period of the periodic table have in common?

Back

Elements in the same period have the same number of energy levels (shells) in their electron configuration.

Front

How are nonmetals characterized?

Back

Nonmetals are characterized as elements that are typically gases or brittle solids at room temperature and are poor conductors of heat and electricity.

Front

What are transition elements?

Back

Transition elements are the d-block elements in the periodic table, known for their ability to form variable oxidation states and colored compounds.

Front

What are the properties of noble gases?

Back

Noble gases are colorless, odorless, and tasteless gases that are non-reactive under standard conditions due to their full valence electron shells.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom or ion in its gaseous state.

Front

What distinguishes metals from nonmetals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity, while nonmetals are usually dull, brittle, and poor conductors.

Front

What are metalloids?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals, often exhibiting a mix of both sets of characteristics.
