Yes there are, both,
Arthropoda ==> Chelicerata (spiders, scorpions, mites, ticks etc) ==> Arachnida (spiders, scorpions) ==> Scorpiones (scorpions).
no , all arachnids and (chelicerata) have no antennae (Spiders , scorpions , pseudo scorpions , ticks and mites) .
No, scorpions are arachnids, or relatively distant relatives of Spiders. Like spiders, scorpions are in the phylum Arthropoda (segmented worms are in the phylum Annelida).
Camel spiders are a type of wind scorpion. They are neither spiders nor scorpions but solifuges.
Spiders are classed as ARACHNIDS, as are some other eight-legged creatures, such as scorpions.
No, scorpions are arachnids, or relatively distant relatives of spiders. Like spiders, scorpions are in the phylum Arthropoda (segmented worms are in the phylum Annelida).

Spiders form a monophyletic group with all modern spiders sharing a common ancestor. This means that all spiders are equally related to scorpions. Some stem groups may have characteristics that are plesiomorphic or "primitive with respect to other spiders" that may make them appear superficially similar to ancient arachnids.
Scorpions are not vertebrates. They do not have a backbone and are classified as invertebrates.
