Strontium

The products of this reaction are strontium chloride, carbon dioxide and water.

Because strontium sulfate is much less soluble in water than strontium chloride, sodium chloride, or sodium sulfate, this reaction is:

Na2SO4 (aq) + SrCl2 (aq) => 2 NaCl (aq) + SrSO4 (s).

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!

Two valence electrons

Strontium in the form of strontium chromate is hazardous because of the chromium it contains. In this form, it is known to cause lung cancer.

If strontium intake is particularly high, it can interfere with bone development.

Strontium's atomic number is 38. So, it has 38 protons and 38 electrons if it's neutral. Strontium is a group 2 element and so has 2 valence electrons. Thus, the rest of the 36 electrons are core electrons.

Both are ions and we should consider the ionic radius, not the atomic radius.

Rubidium ion (Rb+) will have a larger IONIC radius than strontium ion (Sr2+).

Both ions have the same electronic configuration. But strontium ion has more number of protons in the nucleus. Hence it will have greater force of attraction between the nucleus and the valence electrons, resulting in smaller size.

Sr2+, 2[I]-

I could not put the dots around the I that represents iodine because the computer does not allow me to, but there is suppose to be eight electrons around it

In January 1990 it cost about $5/oz.

The chemical formula for strontium and nitrogen is Sr3N2.

No, Strontium is an alkaline earth metal which exists in solid state.

Strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when exposed to air.

5s orbital

Yes it is
First of all, never say, "Is a substance flammability,' because in college professors will not just drill you, you'll have a bad reputation around campus for low knowledge of grammar; say is strontium FLAMMABLE. And yes, strontium is flammable.

Strontium is slightly soluble in water

If you mean "electron configuration" then: Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 Short-hand version: [Kr] 5s^2 Note: The "^" symbol means the the following number is in the form of a superscript.

A chemical equation is a written symbolic representation of a chemical reaction. The reactant chemical(s) are given on the left-hand side and the product chemical(s) on the right-hand side. The law of conservation of mass states that no atoms can be created or destroyed in a chemical reaction, so the number of atoms that are present in the reactants has to balance the number of atoms that are present in the products

phospheric acid= H3PO4

strontium oxide= SrO

It is ionic bond

it feels like my hands ;)

The outermost principle energy level for strontium is the 5th energy level.

Lithium is less dense than strontium. The density of lithium is about 0.534 g/cm3, whereas the density of strontium is about 2.54 g/cm3.
