From a chemical standpoint, indium has two main oxidation states, which are +1 and +3, with latter being more stable. It is a post-transition metal which lies between gallium (atomic number 31) and thallium (atomic number 81) in group 13 of the Periodic Table and acts somewhat between them in a chemical sense; the only common oxidation state of gallium is +3 and thallium shows +1 more often than +3, with thallium(III) being a moderately strong oxidizing agent, while indium(III) is stable and indium(I) is a powerful reducing agent. It is usually found as a compound in zinc ores.
Physically, indium is a fairly soft (Mohs hardness 1.3, Brinell hardness 8.83 Mpa) silvery metal with a melting point of 156.5985 °C (313.8773 °F) and a boiling point of 2072 °C (3762 °F). The atoms in pure solid indium arrange in a tetragonal structure.
What else can I help you with?
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
How are indium mirrors made?
Indium mirrors are typically made by depositing a thin layer of indium metal onto a substrate using techniques such as physical vapor deposition or sputtering. The indium layer is then polished to achieve the desired reflective properties. Indium mirrors are known for their high reflectivity in the infrared spectrum.
Does a chemical reaction change physical properties or chemical?
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
Which element does gallium have more in common with germanium or indium?
Gallium has more in common with indium. Both gallium and indium are part of the same group on the periodic table, Group 13 (or Group IIIA), so they share similar chemical properties and trends. Germanium, on the other hand, is in Group 14 and therefore differs in its properties from gallium.
Changes in properties of matter are called?

Does chemical and physical properties are probably the same?
No. Chemical and physical properties are different.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.

What is the formula for indium oxide?
The chemical formulasof indium oxides are InOand In2O3.
How similar might you expect the chemical properties of gallium and indium to be?
Gallium and indium are both in the same group of the periodic table (Group 13), so they have similar chemical properties. Both elements are soft metals with low melting points and are often used in electronic applications due to their unique properties. However, gallium is more reactive than indium and has a lower melting point.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Does copper have chemical or physical?
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
