Atoms and the Periodic Table Test Practice #1

Front

What are transition metals?

Back

Transition metals are the most common metals found in groups 3 through 12 of the periodic table, known for their ability to form various oxidation states and colored compounds.

Front

What are noble gases?

Back

Noble gases are the most inactive elements, located in group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

How do you determine the number of shells in an atom?

Back

The number of shells in an atom corresponds to the period (row) it is in on the periodic table.

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

Which element has 4 shells and 7 valence electrons?

Back

Bromine has 4 shells and 7 valence electrons.

Front

What is the atomic mass unit (AMU) of Beryllium?

Back

Beryllium has an atomic mass unit (AMU) closest to 9.

Front

What determines the atomic number of an element?

Back

The atomic number of an element is determined by the number of protons in its nucleus.

Front

Which element has 6 protons and 8 neutrons?

Back

An element with 6 protons and 8 neutrons is Carbon.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are alkali metals?

Back

Alkali metals are highly reactive elements found in group 1 of the periodic table, known for having one electron in their outermost shell.
