Identify the incorrect match:Name IUPAC Official Name(a) Unnilunium (i) Mendelevium(b) Unniltrium (ii) Lawrencium(c) Unnilhexium (iii) Seaborgium(d) Unununnium (iv) Darmstadtium
To solve this problem, we need to identify the incorrect match between the given element names and their IUPAC official names.Let's analyze each option:(a) Unnilunium (i) Mendelevium:• Unnilunium is the old name for the element with atomic number 101.• The IUPAC official name for this element is Mendelevium.• This match is correct.(b) Unniltrium (ii) Lawrencium:• Unniltrium is the old name for the element with atomic number 103.• The IUPAC official name for this element is Lawrencium.• This match is correct.(c) Unnilhexium (iii) Seaborgium:• Unnilhexium is the old name for the element with atomic number 106.• The IUPAC official name for this element is Seaborgium.• This match is correct.(d) Unununnium (iv) Darmstadtium:• Unununnium is the old name for the element with atomic number 111.• The IUPAC official name for this element is Roentgenium, not Darmstadtium.• This match is incorrect.Therefore, the incorrect match is option (d), (iv). This corresponds to Option 3.
