Question

Copper and gold have similar reactive properties. On the Periodic Table of the Elements, these elements are most likely to...

Select one :

A || have nearly the same mass.

B || have the same number of protons.

C || be in the same group.

D || be in the same period.

Answer 1

Answer:

C. Be in the same group

Explanation:

Most elements in the same group have similar properties.

Answer 2

Copper and gold have similar reactivity properties, thus they are most likely to belong to the same group. Thus option C is correct.

The reactive properties or the chemical properties of an element have been based on the presence of the valence electrons in the atom.

The valence electrons in the atom are responsible for the bond formation and other intermolecular interactions thereby contributing to the reactivity of the atom.

In the periodic table, on moving down the group, the number of valence electrons to the atoms remains constant with the increase in the size of the atom. Thus, the elements belonging to the same group have consisted of similar reactivity properties.

Copper and gold have similar reactivity properties, thus they are most likely to belong to the same group. Thus option C is correct.
