An element whose IUPAC name is ununtrium (Uut) belongs to

Options

A. s - block element
B. p - block element
C. d - block element
D. Transition element

Answer

To determine the block to which the element with the IUPAC name ununtrium (Uut) belongs, we can follow these steps:

### Step 1: Identify the Atomic Number
The name "ununtrium" is derived from Latin roots where "un" means one and "tri" means three. Therefore, ununtrium corresponds to the atomic number 113.

**Hint:** Remember that the prefix "un" indicates 1 and "tri" indicates 3, which together give you the atomic number.

### Step 2: Locate the Element in the Periodic Table
Now that we know the atomic number is 113, we can locate it in the periodic table. Elements are arranged in order of increasing atomic number.

**Hint:** Use the periodic table to find the position of element 113.

### Step 3: Determine the Group
Element 113 is positioned in group 13 of the periodic table. Groups are the vertical columns in the periodic table, and group 13 includes elements such as aluminum and gallium.

**Hint:** Groups are numbered from 1 to 18 in the periodic table.

### Step 4: Identify the Block
Elements in group 13 belong to the p-block of the periodic table. The p-block consists of groups 13 to 18 and includes the elements that have their outermost electrons in p orbitals.

**Hint:** Recall that the periodic table is divided into s, p, d, and f blocks based on the electron configuration of the elements.

### Conclusion
Thus, the element ununtrium (Uut), with atomic number 113, belongs to the **p-block** of the periodic table.

**Final Answer:** Ununtrium (Uut) belongs to the p-block.
