Strontium (Sr) is number 38
Strontium is an alkaline earth metal; group 2 and period 5 in the periodic table of Mendeleev.
There 38 protons in strontium. Strontium is No. 38 in the Periodic Table.. This indicates the number of protons and electrons in a neutral atom of strontium . Strontium is named after the Scottish village, Strontian, in the Highlands of Scotland, where it was first discovered.
Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.
The atomic number of strontium (Sr) is 38.The atomic weight of Sr is 87.62 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
The name is "strontium sulfite" and the formula is SrSO3.
Period 5 with the atomic number of 38.
Strontium is group 2 element and is the second element in period 5 with an atomic number of 38
The element with 38 electrons is Strontium (Sr). Strontium is an Alkaline Earth Metal in Period 5 of the Periodic Table. Strontium has 38 electrons, 5 electron shells and 2 electrons in the outer shell.
