It doesn't seem likely. Selenium isn't terribly reactive, and selenium monochloride exists in equilibrium with a different kind of selenium chloride, chlorine gas, and elemental selenium; this indicates that there's not a huge energy difference between the uncombined elements and the compound, as you would expect there to be if they "blew up" when combined.
chlorine is more reactive than selenium. Chlorine needs one electron to form octet whereas selenium needs two.
Selenium dioxide has a covalent or molecular bond.
It is a covalent bond.
Xenon as it is a noble gas. Noble gases are inert and do not react with anything. Selenium is a solid Chlorine is a green coloured highly reactive poisonous gas. Carbon is a non-metallic solid.
B. moderately polar covalent
A sulfur atom is larger than an oxygen atom.
Chlorine will have the smallest atomic radius, bromine the largest.
Rubidium 1+ Barium 2+ Chlorine 1- Selenium 2- Francium 1+
slicon of course
Gold form compounds with sulfur, selenium, tellurium, fluorine, chlorine etc.
Pool worms they come from the trees and blow into the pool. Keep up on the chlorine, make sure the levels are right and use the pool cover when it is not in use. The chlorine will eventually kill them and they will be filtered out.
