The electronic configuration of element with atomic number 33 is 1s22s22p63s23p63d104s24p3
As, its last shell have five electrons
and hence, its group is 10 + 5 = 15th or V A.
Hence,it lies in the 15th group.

Explanation:

Atomic number is the number of protons in the nucleus of an atom. It determines the chemical properties of an element and its position in the periodic table. The periodic table is arranged in a specific order based on the atomic number of elements.

- The first group of elements in the periodic table is the alkali metals, which have one valence electron.
- The third group of elements is the boron group, which have three valence electrons.
- The seventh group of elements is the halogens, which have seven valence electrons.

Therefore, an element with an atomic number of 33 will be placed in the fifteenth group of the periodic table because it has five valence electrons. This group is also known as the nitrogen group or pnictogens. The elements in this group include nitrogen, phosphorus, arsenic, antimony, and bismuth.

In summary, the position of an element in the periodic table is determined by its atomic number and the number of valence electrons. An element with an atomic number of 33 will be placed in the fifteenth group of the periodic table because it has five valence electrons.
