Aspace probe identifies a new element in a sample collected from an asteroid. successive ionization energies (in attojoules per atom) for the new element are shown below.
i1 i2 i3 i4 i5 i6 i7
0.507 1.017 4.108 5.074 6.147 7.903 8.294

to what family of the periodic table does this new element probably belong?
1(1a)
2(2a)
13(3a)
14(4a)
15(5a)
16(6a)
17(7a)
18(8a)

If you observe the IEs sequentially, there is a large gap between the 2nd and 3rd. This suggests it is difficult to remove more than 2 two electrons. Elements that lose two electrons to become more stable are found in the Group 2A (2 representing the number of electrons in the outermost valence shell).

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
