Fall 2023 semester review

Front

What type of bond involves a metal and a nonmetal?

Back

Ionic bond is formed when a metal atom transfers electrons to a nonmetal atom, resulting in the formation of charged ions that attract each other.

Front

Do nonmetals gain or lose electrons during chemical reactions?

Back

Nonmetals gain electrons during chemical reactions to achieve a full outer shell, often forming anions.

Front

What is the metric unit for volume?

Back

The metric unit for volume is the liter (L), which is commonly used to measure liquids.

Front

Which element has the highest electronegativity?

Back

Fluorine has the highest electronegativity, meaning it has a strong tendency to attract electrons.

Front

What is the name of the compound C2H4?

Back

The name of C2H4 is dicarbon tetrahydride, commonly known as ethylene.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs between two atoms when one atom donates an electron to another, resulting in the formation of oppositely charged ions.

Front

What is electronegativity?

Back

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

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the significance of the octet rule in chemistry?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to greater stability.

Front

What is a nonmetal?

Back

Nonmetals are elements that typically lack the properties of metals, such as conductivity and malleability, and often gain electrons in chemical reactions.
