Electrons & the Periodic Table Test Review

Front

What are the alkali metals?

Back

The alkali metals are a group of elements in Group 1 of the periodic table, including lithium (Li), sodium (Na), and potassium (K), known for their reactivity and tendency to lose one electron.

Front

What is the maximum number of electrons that can occupy the s block?

Back

The s block can hold a maximum of 2 electrons.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, such as silicon (Si) and germanium (Ge).

Front

What does the p-block of the periodic table represent?

Back

The p-block includes groups 13 to 18 of the periodic table and contains elements that have their outermost electrons in p orbitals.

Front

Who is Dmitri Mendeleev?

Back

Dmitri Mendeleev was a Russian chemist who created the first widely recognized periodic table and predicted the existence of undiscovered elements.

Front

What is the significance of the periodic law?

Back

The periodic law states that the properties of elements are a periodic function of their atomic numbers, leading to the arrangement of elements in the periodic table.

Front

What are the main characteristics of metals?

Back

Metals are typically shiny, good conductors of heat and electricity, malleable, and ductile.

Front

What are the main characteristics of nonmetals?

Back

Nonmetals are generally dull, poor conductors of heat and electricity, and can be gases, liquids, or brittle solids at room temperature.

Front

What is the role of valence electrons in chemical bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming chemical bonds with other atoms.

Front

What is an atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.
