I presume your meaning when you react an alkali metal in an acid to release H2 gas. Your left in that case with Water & a salt
Regards
No, most nonmetals are on the RIGHT upper corner of the periodic table. The only nonmetal on the left side is hydrogen.
Elements on the left side of the Periodic Table are "Alkali Metals". There is also one non-metal element. H(hydrogen)
Hydrogen is a non-metal. Hydrogen is a colorless, odorless, and tasteless gas that is the most abundant element in the known universe. It is the lightest and simplest having only one proton and one electron. Although hydrogen has an ns1 electron configuration just like alkali metals, it is still not metal because it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than other alkali metals. Because hydrogen is a nonmetal and forms H–(hydride anions), it is placed above the halogens in the periodic table. Hydrogen also forms H2dihydrogen like halogens. However, hydrogen is very different from halogens. Hydrogen has a much smaller electron affinity than halogens.
All periods begin with an alkali metal, excepting the first which begin with hydrogen..
Sodium hydroxide, or NaOH, is neither a metal or a non-metal. It is an ionic compound.It is composed of sodium, which is a metal, and oxygen and hydrogen which are non-metals.See the Related Questions to the left for more information.
No, silicon is not an alkali metal. Silicon is a metalloid located in Group 14 of the periodic table, while alkali metals are located in Group 1. Silicon shares some properties with metals and non-metals.
Hydrogen can be considered as a non metal. It is placed to the left of the periodic table.
Hydrogen
alkali and alkaline earth on the left/ transition metal middle /mettaloids are on the right
on the left hand side of the Periodic Table (group 1)
Alkali metals are all of the elements on the far left hand side of the Periodic Table with the exception of hydrogen. They are all highly reactive metals that also react vigorously with water.
The only nonmetal to the left of the zigzag line in the periodic table is hydrogen (H). It is positioned above group 1 on the periodic table because it shares some chemical properties with the alkali metals, but it is not a metal.
