Why would a scientist most likely chose to perform a simulation instead of a lab experiment or field observation? O The lab experiment might be dangerous or too difficult to do.
O Simulations rely on mathematical analysis and have one correct answer.
Field observations are less accurate than computer simulations.
Simulations are more accurate than lab work.

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.
