In 1998, paleoanthropologist Rick Potts, of the Smithsonian Institution, published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts provided evidence to support his claim that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Why might this not be the best article to reference? a) Potts has no authority.
b) Potts was not objective.
c) The article may not reflect current knowledge.
d) The article was not reviewed bu Potts's peers.

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.
