Periodic table valence electrons labeled3/31/2024 ![]() ![]() Also pure gallium is resistive to the attack of mineral acids, because the oxide layer formed on the outer surface of gallium protects the inner metal.At higher temperatures, gallium also reacts with oxygen to form gallium oxide.Gallium reacts with chalcogens elements only at higher temperatures.At room temperature, gallium is not so reactive as it forms a protective oxide layer on it.Chemical properties of GalliumĬhemical properties of gallium are mentioned below. Gallium has many isotopes, but out of these isotopes, 69Ga is the most abundant (around 60%).Gallium becomes brittle solid at lower temperatures.The melting point of gallium is 29.7 ☌ and its boiling point is 2400 ☌.Gallium is a soft metal having a silvery blue color.Physical properties of gallium are mentioned below. The physical and chemical properties of gallium element are mentioned below. Hence it should not be stored in a glass container. If you hold a gallium in your hand, then it will melt down due to the warmth of your hand.Its melting point is just very close to room temperature (i.e 29.7 ☌), while its boiling point is much higher (i.e 2400 ☌). The difference between the melting point and boiling point of gallium is high.Gallium is a soft metal that can be cut even with a kitchen knife.Gallium is the 34 th abundant element found from the earth’s crust.Earth’s crust contains around 0.0019% of gallium by weight.The name gallium was derived from the latin word “gallia”.Interesting facts about gallium element are mentioned below. So the last electron of gallium enters the p-subshell or p-orbital. The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.įor example the electron configuration of gallium is 3d 10 4s 2 4p 1. How can you determine the blocks-wise position of elements? Orthorhombic Melting point 302.9 K or 29.7 ☌ or 85.5 ☏ Boiling point 2673 K or 2400 ☌ or 4352 ☏ Density 5.904 g/cm 3 Main isotope 69Ga Who discovered Gallium and when?īefore knowing this reason, first of all I want to ask you a simple question.
