What is the period number for strontium?

Strontium (Sr) is number 38


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 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.


What is the atomic number of strontium?

What is the reaction equation for strontium oxalate and water?

The reaction between strontium oxalate and water produces strontium oxalate solution. The balanced chemical equation for this reaction is SrC2O4 (s) + H2O (l) → SrC2O4•nH2O (aq), where n is the number of water molecules that coordinate with strontium oxalate in the resulting solution.

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 the atomic number for strontium chloride?

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.


In a correctly written nuclear equation what is true about the total mass number on the reactant side as compared to the total mass number on the product side?

the total mass number should be equal on both sides. conservation of mass law.


When balancing a nuclear equation what two quantities are conserved when balancing a nuclear equation?

In a nuclear equation, the total number of protons and neutrons is conserved. This means that the sum of the mass numbers and the sum of the atomic numbers must be the same on both sides of the equation before and after the reaction.


What is an isotope of strontium that has 52 neutrons?

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.


What is the number of valence electrons and oxidation number of strontium?

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.


When strontium reacts with water it forms strontium hydroxide and hydrogen gas is released write the balanced equation for the reaction between strontium and water?

The balanced equation for the reaction between strontium and water is: 2 Sr + 2 H2O → 2 Sr(OH)2 + H2 This equation shows that two moles of strontium react with two moles of water to produce two moles of strontium hydroxide and one mole of hydrogen gas. The equation is balanced as the number of atoms of each element is the same on both sides of the reaction.
