question deals periodic trends. allow me simplify. trend atomic radius is:

-increases going down group
-decreases going left right across period

in order of decreasing atomic size means biggest atom first, followed each successive smaller atom. looking for: biggest radius---> smallest radius. use periodic table: atom closest bottom left of table biggest. cesium. need apply knowledge above figure out barium smaller cesium b/c right of it. , bromine smaller arsenic b/c right of it. neon smallest because closer top right other atom in list, expected b/c of it's noble gas configuration.

***biggest ----> smallest radius: cesium, barium, bismuth, arsenic, bromine, neon.

edit: every other answer wrong far. arsenic has bigger radius bromine, according periodic trend.

place following elements in order of decreasing atomic size: bismuth, bromine, neon, cesium, barium, , arsenic?

Is glass fibre really made from glass?

yes. glass fiber (or fibre) thin strand of glass can used insulation, communication, , reinforcement being woven fabric materials including cloth , tape. thin glass strong if pulled (in tension) large sheets of glass, brittle , broken if cut or bent. therefore coated or included in align or keep fluffy, etc. fiberglass (or brand name fiberglas) combination of glass fibers in mat or cloth form soaked in resin hardens hold shape - glass strengthens object , resin protects glass ino people tthis stupid question im kid , wondering :) Arts & Humanities Visual Arts Sculpture Next

Is there such thing called a winged spider?

-
of all's answers comical, least. however, have clarify things amateur biologists, here. arachnids classified such having 2 segments bodies, not number of legs.solpugids arachnids, yet have ten legs, , no venom. solpugids include such animals "sun spiders" , "camel spiders" (which massive, , qualify writers call "nightmare fuel"... trust me... few tours in iraq, have seen several of these things). insects have 3 segments bodies. insects have 4 legs... 6-legged flying instects have 8 (yep... wings count "legs") or 10, depending on number of wings. pic in question, photoshopped, sure. no species of arachnid has wings. , if closely, hymenoptera wings.... bee wings, actually. if recall opening monologue "bee movie" (shut up... have kids), you'd recall line says "wings small, , wrong shape", or words effect. if bee can barely manage flight, spider similar wings wouldn't able waft own farts (if spider digestive...
