Question

which one of following is not representative element?​

Answer 1

Explanation:

The transition elements are elements where the d orbitals (groups 3–11 on the periodic table) are filling. among the following Tantalum (Z=73) is not a representative element it is a transition element.

Answer 2

Tantalum is not a representative element.

• a representative element.The representative elements are the elements where both the s and p orbitals are full.
• a representative element.The representative elements are the elements where both the s and p orbitals are full. While transition elements are the elements where along with s and p orbitals, d orbitals are also filled.
• a representative element.The representative elements are the elements where both the s and p orbitals are full. While transition elements are the elements where along with s and p orbitals, d orbitals are also filled. Transition elements are hard and form paramagnetic compounds, as well as coloured ions as well as compounds.
• a representative element.The representative elements are the elements where both the s and p orbitals are full. While transition elements are the elements where along with s and p orbitals, d orbitals are also filled. Transition elements are hard and form paramagnetic compounds, as well as coloured ions as well as compounds. Tantalum has an atomic number of 73 and is considered as a transition element and not as a representative element.

Hence, b is the correct answer.
