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!
strontium is alkaline earth metal and its oxide is a basic alkaline.
Is strontium a Latin or Greek name?
"strontium" as with all elements takes it's name from the Latin word "Strontia"
Name and formula for the compound formed by strontium ions and sulfite ions?
The name is "strontium sulfite" and the formula is SrSO3.
How do you write carbonic acid and strontium hydroxide in neutralization reaction?
Use a number 2 pencil
What is the oxidation number of carbon in strontium carbonate?
In the carbonate CO32- the sum of the oxidation numbers is the ionic charge (true for all poyatomic ions) O is assigned -2 so C has +4. (maths 4 +(-6) = -2)
Is the element strontium not found in nature?
Strontium occurs naturally in four stable isotopes: 84, 86, 87, 88. A flame test gives bright red color if strontium is present. Strontium salts are used in fireworks for this bright red color.
What elements has the lowest first ionization energy Phosphorus scandium strontium or oxygen?
strontium
What is the chemical formula for strontium arsenate?
The chemical formula of strontium arsenate is Sr3(AsO4)2.
Is lithium likely to form an ionic compound with strontium?
No, lithium and strontium are both metals. Ionic compounds occur between metals and non-metals. They are both positively charged, so an ionic bond would not be attainable.
Why is it not surprising that strontium phosphate is insoluble?
Most phosphate are insoluble, unless they are group 1A or ammonium phosphates.
How many valense electrons does strontium have?
There are 2 valence electrons in Radium. There are 2 valence electrons in Radium.
What is the pH of a 0.356 M aqueous solution of strontium hydroxide?
- log(0.356 M Sr(OH)2)
= 0.4486
14 - 0.4486
= 13.5 pH

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.
0.5077g
How can compounds that contain strontium and barium could be use in fireworks?
Because Strontium and Barium provide brilliant red and orange colors.
What is the greek name of strontium?
There is no Ancient Greek name for Strontium. It wasn't discovered until 1790.
How might a scientist distinguish the following compounds strontium chloride and potassium chloride?
If you heat something containing strontium until it glows it should tend to glow red. If you heat something containing potassium until it glows it should tend to glow yellow.
