Copper (Cu) belongs to group 11 of the Periodic Table, and two elements with similar properties are silver (Ag) and gold (Au). These elements share similar metallic characteristics, such as high electrical conductivity, malleability, and ductility. Additionally, they exhibit similar chemical behaviors, particularly in forming compounds and participating in metallic bonding.
You would likely find five elements with very similar properties in the same group of the periodic table. For example, elements in Group 1 (alkali metals) like lithium, sodium, potassium, rubidium, and cesium share similar characteristics such as being soft, highly reactive metals with low melting points and easily losing electron to form cations.
Elements in the same group as zinc would be expected to have similar properties.
Two elements in the same group are more likely to have similar properties. This is because elements in the same group have the same number of valence electrons, which largely determines their chemical behavior and reactivity. In contrast, elements in the same period have different numbers of valence electrons and can exhibit a wider range of properties.
Oxygen, Sulphur, Selenium, Tellurium, Polonium, and Livermorium. Have similar chemical properties as they are all in Group VIA (16). However, the last two are radio-active and not found in the open lab.
Any element in the alkali metal group would have similar chemical properties, for example they all react easily to water.
Two elements that would have similar properties are calcium (Ca) and magnesium (Mg). Both elements are alkaline earth metals, have similar reactivity, and form similar compounds. Additionally, they have similar atomic structures with two electrons in their outer shell.
The two elements with similar chemical properties to iodine are bromine and chlorine. They all belong to the halogen group in the periodic table, sharing similar reactivity and chemical behavior.

plutonium, and heluim
Elements in the same group as zinc would be expected to have similar properties.
Bromine and iodine are two elements that have properties similar to chlorine. They are all halogens and share common characteristics such as high reactivity and the ability to form compounds with other elements easily.

Johann Dobereiner grouped elements with similar properties into triads. In these triads, he observed that the properties of the middle element were the average of the other two.
Plutonium and neptunium are two elements that have properties similar to uranium. They belong to the same actinide series and share similar chemical and physical characteristics, such as radioactive decay and the ability to form multiple oxidation states.
Platinum and rhodium are two elements that have similar properties to nickel and palladium. They are all transition metals that exhibit high melting points, resistance to corrosion, and are commonly used in catalytic converters and jewelry.
There is no fully objective answer to this question. Many chemists would consider that two lanthanide elements with atomic numbers differing by only one would be likely to qualify. Another possibility is the pair zirconium and hafnium. These are very similar in most chemical characteristics but differ greatly in electron capture tendencies in nuclear reactors.
Bromine and iodine are two elements that have similar properties to chlorine because they belong to the same group in the periodic table, known as the halogens. They share characteristics such as being highly reactive nonmetals with similar bonding behavior and reactivity.
