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.
Strontium is in the 5th period of the periodic table.
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.

The atomic number for strontium chloride is determined by the element strontium, which has an atomic number of 38. Since chloride is an anion with a charge of -1, it does not affect the overall atomic number of the compound.

Strontium is an alkaline earth metal; group 2 and period 5 in the periodic table of Mendeleev.
Strontium-88 is an isotope of strontium that has 52 neutrons. It has an atomic number of 38, therefore the total number of neutrons (52) is obtained by subtracting the atomic number from the mass number.
Strontium has 2 valence electrons because it is in Group 2 of the periodic table. The oxidation number of strontium is typically +2, as it tends to lose those 2 valence electrons to achieve a stable electronic configuration.

You can tell how many protons an element has from its atomic number. So the atomic number of Strontium is 38..so it has 38 protons.
