The fossils of a few organisms are shown below. the first image is a bird, the second image is a dinosaur, and the third image is an archaeopteryx. the dinosaur fossils were obtained from the lower sedimentary layer, and archaeopteryx was found above it. the fossils of the bird were found on the topmost layer, which suggests that they’re the . this information also suggests that archaeopteryx .

Using the periodic table, determine which material is most likely a good conductor

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
