The electronic configuration clearly suggest that it is a d-block element (having contiguration (n – 1) d1– 10 ns0 – 2) which starts from III B and goes till II B. Hence with d3 configuration it would be classified in the group.

Answer:
To determine the group of an atom based on its electronic configuration, we need to look at the outermost electron shell. In this case, the atom has the electronic configuration: 1s2 2s2 2p6 3s2 3p6 3d3 4s2.
Here, the outermost electron shell is the 4th shell, which contains 2 electrons in the 4s orbital. The group number of an element is defined by the number of valence electrons it has, which are the electrons in the outermost shell.
1. Valence Electrons:
The valence electrons are the electrons in the outermost shell, which are responsible for the chemical properties of an atom. In this case, the atom has 2 valence electrons in the 4s orbital.
2. Group Determination:
To determine the group of an element, we need to look at the periodic table. The periodic table is divided into columns called groups, which are numbered from 1 to 18. Each group contains elements with similar chemical properties.
In the case of this atom, it has 2 valence electrons, which corresponds to group 2. Therefore, the atom belongs to group 2.
Summary:
Based on the electronic configuration 1s2 2s2 2p6 3s2 3p6 3d3 4s2, the atom belongs to group 2.
