What is the period number for strontium?
Strontium (Sr) is number 38
What is the nuclear decay equation for strontium 90?
Since the atomic number of Sr is less than 90, Sr undergoes beta decay. Beta decay is when the element decays into another element and a neutron actually breaks apart (sort of) into an electron and proton; the proton attaches to the other element, but the electron stays alone. Thus: 90------>90 Y+e0-1 38 Sr--->39 Y+e *there should only be one e, and the 0 and -1 should be in front, just like with the elements, but the format deletes the extra spaces so i put it like that for clarity's sake. sorry!
Why is the first ionisation energy of strontium larger than the first ionisation energy of rubidium?
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.
How many protons in strontium?
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.
What is the atomic number of strontium?
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!
What is the missing number in this nuclear equation 233 Pa?
The question cannot be answered since there is no equation there!
What is the period number for strontium?
Strontium (Sr) is number 38
What is the number of valence electrons and oxidation number of strontium?
Strontium is located in group 2 of the periodic table. Hence it has two valence electrons. The oxidation number atomic strontium is 0 where that of strontium ion is +2.
What is the nuclear equation for beta decay of cesium-137?
The number 87 when referred to francium is that element's atomic number. The most common isotope of francium is 223, which has a half-life of 22 minutes and decays by beta-negative emission into radium-223.

What is strontium's atomic number written as a positive integer?
All atomic numbers are positive integers. Strontium's atomic number is 38.
What is the nuclear decay equation for strontium 90?

Beta decay is when the element decays into another element and a neutron actually breaks apart (sort of) into an electron and proton; the proton attaches to the other element, but the electron stays alone. Thus: 90------>90 Y+e0-1 38 Sr--->39 Y+e *there should only be one e, and the 0 and -1 should be in front, just like with the elements, but the format deletes the extra spaces so i put it like that for clarity's sake. sorry!
What is the element represented by the symbol Sr?
It represents the element with the atomic number of 38 Strontium
