Chapter 6, Problem 39A

Interpretation Introduction

Interpretation:

The names of the element of atomic number 117 to 120 needs to be determined.

Concept introduction:

The Latin names of the digits (0 to 9) are put together in the order in which they appear in the atomic number of a particular element and the suffix ‘ium’ is added at the end,

Answer to Problem 39A

1. The name of element of atomic number 117 is Ununseptium.
2. The name of element of atomic number 118 is Ununoctium.
3. The name of element of atomic number 119 is Ununennium.
4. The name of element of atomic number 120 is Unbinilium.

Explanation of Solution

The table of name of digits in the IUPAC naming of elements is as follows:

Digits	Name
0	nil
1	un
2	bi
3	tri
4	quad
5	pent
6	hex
7	sept
8	oct
9	enn

For the element 117, name is,

117=Un+un+sept+ium=Ununseptium

For element 118,

118=Un+un+oct+ium=Ununoctium

For element 119,

119=Un+un+enn+ium=Ununennium

For element 120

120=Un+bi+nil+ium=Unbinilium

Conclusion

Using the Latin names of the digits (0 to 9), the IUPAC name of elements can be determined.
