Unit 3 Review- Chem

Front

What is a transition metal?

Back

Transition metals are elements that have partially filled d orbitals and are found in groups 3-12 of the periodic table. They are known for their ability to form various oxidation states and complex ions.

Front

Which element is an example of a transition metal?

Back

Iron (Fe) is an example of a transition metal.

Front

What is the atomic radius trend in the periodic table?

Back

Atomic radius generally decreases across a period from left to right and increases down a group.

Front

Which group in the periodic table has the smallest atomic radius?

Back

Noble Gases have the smallest atomic radius.

Front

What is an orbital in the context of atomic structure?

Back

An orbital is a region of space around the nucleus of an atom where there is a high probability of finding an electron.

Front

How many electrons can the first energy level hold?

Back

The first energy level can hold a maximum of 2 electrons.

Front

How many electrons can the second energy level hold?

Back

The second energy level can hold a maximum of 8 electrons.

Front

How many electrons can the third energy level hold?

Back

The third energy level can hold a maximum of 18 electrons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of valence electrons in chemical reactions?

Back

Valence electrons determine how an element will react chemically and how it will bond with other elements.
