Answer:
5
Explanation:
Let us look at the values very closely. It is easy to see that the first to the fifth ionization energies of the element are closely related to each other. Recall that the ionization energy increases as the the number of electrons removed from the outermost shell of the atom increases. Hence E1<E2<E3......... The first five ionization energies suggest the removal of valence shell electrons.
However, the sixth and seventh ionization energies shows a jump, the ionization energy suddenly increases by a very high magnitude. This can not suggest the removal of a valence shell electron but the removal of inner or core electrons. Hence the answer.

Answer:
172.385 g/mol
Explanation:
Magnesium Tartrate is C4H4MgO6
C - 12.01 g/mol
H - 1.01 g/mol
Mg - 24.305 g/mol
O - 16.00 g/mol
12.01(4) + 1.01(4) + 24.305 + 16(6) = 172.385 g/mol
Answer:
Molar ratio of the compound is 1:1 and the type of hydrate is Mono hydrate.
Explanation:
From the given,
Mass of sodium carbonate 
= 8.85 g
Loss mass 
= 1.28 g
Actual weight of sodium carbonate = 8.85 g - 1.28 g = 7.57 g
Therefore, the compound has only one water molecule.
Molecular formula of the compound is 
an name of the compound is <u>sodium carbonate mono hydrate.</u>
Hence, the type of the compound is Mono hydrate.
