Chemistry Unit 2 Review

Front

What is the definition of a nonmetal?

Back

Nonmetals are elements that are typically poor conductors of heat and electricity, have high ionization energies and electronegativities, and are often brittle in solid form.

Front

What are the characteristics of metals?

Back

Metals are typically lustrous, malleable, ductile, good conductors of heat and electricity, and tend to lose electrons during chemical reactions.

What is the electron configuration for Nickel?

Front

What is a metalloid?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals, and they can exhibit characteristics of both.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configurations, and recurring chemical properties, allowing for the prediction of element behavior.

Front

What is the definition of an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.

Front

What is the difference between an anion and a cation?

Back

An anion is a negatively charged ion (gained electrons), while a cation is a positively charged ion (lost electrons).

Front

What is the definition of electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

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 bonds with other atoms.
