Question

an element have IUPAC name un-nil-ennium. the atomic number of element is

109
102
119​

Answer 1

Answer:

Since scientists are still discovering new elements, there is often a fight over names. Sometimes, the element found would have already been discovered in a different period. Hence to avoid confusion over names, they have come up with a nomenclature.

These are the keywords for the numbers based on which names are assigned:

0 - nil

1 = un

2 - bi

3 - tri

4 - quad

5 - pent

6 - hex

7 - sept

8 - oct

9 - enn

Now if an element has an atomic number of 103, then the name is assigned as:

1 = un, 0 = nil, 3 = tri, and finally 'ium' is added at the end.

→ un + nil + tri + ium = unniltrium

Now according to the question, the given name is unnilennium. Breaking them into parts we get:

→ unnilennium = un + nil + enn + ium

Refering to the table for naming, we can assign each of the name a number. Assigning numbers we get:

→ un = 1, nil = 0, enn = 9

Therefore the element having unnilennium is the element with atomic number 109.

Answer 2

Number Root:-

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

The name is derived directly from the atomic number of the element using the above Latin numerical roots.

★un = 1

★nil = 0

★enn = 9

Atomic number of un - nil - ennium is 109!!!
