In our model, the dwarf planet Pluto, which is 40 au’s away from you he sun in real life, is about 11 inches from the sun. If we were to add the closest star- Proxima Centauri( which is 4.3 light years away from our sun, and 1 light year equals 65,000 AU’s),approximately how much longer would our model have to be?

In the diagram below, the northern hemisphere would be in what season at position a a. fall b. winter c. summer d. spring

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.

In general, are there any major differences that you can see? explain
