Finely powdered strontium metal is sufficiently reactive to ignite spontaneously in air. It reacts with water quickly (but not violently like the Group 1 metals) to produce strontium hydroxide and hydrogen gas. Strontium and its compounds burn with a crimson flame and are used in fireworks. Strontiumâs Periodic Table Neighborhood Strontium is a Group 2 Alkaline earth metal. It usually exists as a divalent ion, Sr 2+, in its compounds. Strontiumâs chemistry is very similar to that of calcium, which sits above it in Group 2.
Best Answer: Valence electrons are found by finding what column (out of the 8 highest) the element is in on a periodic table. Neon lies in the 8th column, so it has 8 valence electrons. Valence refers to the Valence Shell - that is the outermost layer of electrons - and is bound to the Octet Rule, meaning that molecules try their hardest to have 8 electrons in their outermost shell (making up the noble gasses, except Helium). Neon has 2 electrons in its inner shell and 8 in its Valence Shell. Cheers!
