What is gallium atomic number 31?
Ga
Gallium (Ga) is a silver metal that has the atomic number 31 in the periodic table. It is located in Group 13 of the periodic table. It has the symbol Ga. Gallium is a relatively soft metal which at temperatures of greater than 29 °c begins to melt.
Is gallium in the p block?
These elements are found in Group 13 (XIII) of the p block in the Periodic Table of Elements. Aluminum, gallium, indium, and thallium are metallic. They each have three electrons in their outermost shell (a full s orbital and one electron in the p orbital) with the valence electron configuration ns2np1.

What is element 33 on the periodic table?
Arsenic, atomic number 33 lies in between phosphorus and antimony in group 15, the so called Nitrogen group of the periodic table.
What is the period number of element having atomic number equal to 32?
5th period, VA group.
What group and period does gallium belong to?
Gallium belongs to p-block elements (because its last or valence electron is in p-subshell). It belongs to period 3rd (because n=3i.e principal quantum no. is 3). And it belongs to 13th group. (because there are 3 electrons in its valence shell, and group no.
Is gallium a solid liquid or gas at room temperature?
Gallium Gallium is a chemical element with symbol Ga and atomic number 31. Classified as a post-transition metal, Gallium is a solid at room temperature.
Is gallium a metal or nonmetal?
Gallium’s location next to the non metals in the periodic table means some of its standard metallic properties are not so metallic, it is a brittle metal and also a poor conductor of electricity. Gallium is used in thermometers and also the produce lasers and diodes.
How is gallium extracted from its ore?
It was extracted from Zinc ores that contained small amounts of Gallium he isolated through electrolysis. Gallium’s location next to the non metals in the periodic table means some of its standard metallic properties are not so metallic, it is a brittle metal and also a poor conductor of electricity.
