Reactivity Quiz

What is chemical reactivity?

• Chemical reactivity is the ability of a substance to absorb light.

• Chemical reactivity is the ability of a substance to undergo chemical reactions and transform into new substances.

• Chemical reactivity is the ability of a substance to remain unchanged.

• Chemical reactivity is the ability of a substance to conduct electricity.

Explain the reactivity series and its significance in chemistry.

• Reactivity series is a measure of the density of metals.

• The reactivity series is used to determine the color of metal compounds.

• It is a tool to calculate the atomic number of metals.

• The reactivity series is a tool used in chemistry to predict the reactivity of metals and their ability to displace one another in reactions.

How many protons are present in the nucleus of an atom?

• The number of protons in the nucleus of an atom is equal to the atomic number of the element.

• The number of protons in an atom is determined by the number of neutrons

• Protons are located outside the nucleus of an atom

• The number of protons in an atom is always 0

Define mass number in relation to an atom.

• Total number of protons and neutrons in the nucleus of an atom.

• Number of isotopes in the atom

• Number of protons in the atom

• Number of electrons in the atom

What is the atomic number of an element?

• Number of electrons

• Number of isotopes

• Number of neutrons

• Number of protons

What does the symbol 'k' represent in chemistry?

• molarity unit

• atomic number

• reaction rate

• rate constant

Why do some elements exhibit higher reactivity than others?

• Color of the element

• Number of protons

• Atomic structure and valence electrons

• Atomic mass

How does the number of electrons in an atom affect its reactivity?

• The number of electrons in an atom has no impact on reactivity

• The number of electrons in an atom determines its reactivity by influencing its ability to gain, lose, or share electrons.

• Atoms with more electrons are less reactive

• Electrons in an atom only affect its color, not reactivity

Discuss the role of valence electrons in determining the reactivity of an element.

• Valence electrons have no impact on reactivity

• Valence electrons determine the color of an element

• Valence electrons play a crucial role in determining the reactivity of an element by influencing how it interacts with other elements to achieve a stable electron configuration.

• Valence electrons are located in the nucleus of an atom

Explain the concept of electron configuration and its impact on reactivity.

• Electron configuration impacts reactivity by influencing how easily an element can gain, lose, or share electrons to achieve a stable configuration.

• Reactivity is solely determined by the number of protons in an atom

• Electron configuration has no impact on reactivity

• Elements with similar electron configurations always have similar reactivities
