All chordates have a notochord (or backbone in vertebrates), a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail at some point in their development. These characteristics are present at least during some stage of their life cycle.
A notochord is a trait ancestral to all chordates. It is a flexible rod-like structure that provides support along the body axis and may persist in some chordates throughout their entire life, while in others it is replaced by the vertebral column.

True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
The four specific characteristics of chordates are that they have a notochord, hollow nerve cord near the notochord, pharyngeal pouches, and an endostyle. Many of these characteristics disappear in invertebrate chordates when they reach adulthood. Most vertebrate chordates retain all four features, such as humans.
No, pharyngeal slits do not disappear before birth in all chordates. In some chordates, such as fish, these slits persist throughout their life and play a role in respiration and feeding. In other chordates, such as mammals, the pharyngeal slits do not persist through adulthood but are present during embryonic development.

all vertebrates are chordates because vertebrates are the sub- group of phylum chordates and also it follow one of the important feature of the chordates i.e. presence of notochord whereas all chordates are not vertebrates because some chordates are cephalochordates, urochordates.
It has a nerve chord running down its back, the defining trait of all chordates.

One phylum trait of a mouse is being classified under the phylum Chordata, which indicates that mice possess a notochord at some stage in their development. This phylum trait is a defining characteristic of all chordates, including mammals like mice.
There isn't a "popular name" for them. The most familiar chordates are the vertebrates, but not all chordates are vertebrates (tunicates, for example, are chordates).
All chordates are deuterostomes, meaning that in all chordates, the anus develops first during embryological development. All chordates are bilaterally symmetric. Most chordates have a complete digestive tract, and a body cavity. Note: not all chordates have these features, but it is believed that their absence in some chordates is secondary. All chordates are of course animals and eukaryotes.
All fish are chordates. Chordates are vertebrates that have a hollow dorsal nerve called a notochord. They also have a central nervous system and gill clefts.
a backbone
Well, no they don't... There's a group of chordates called Agnatha which basically contains all the jawless chordates. And there are obviously limbless chordates present, the fishes and the snakes being the most well-known of the examples...
Yes, chordates typically have a coelom. The coelom is a body cavity lined with mesoderm that surrounds the internal organs, providing space for organ movement and protection. It is considered an important characteristic of chordates, although not all chordates have a well-developed coelom.
all have four valence electrons
