Elements that have 2 electrons in the 4s sublevel are those found in Group 2 of the Periodic Table, also known as the alkaline earth metals. The first two elements in this group are calcium (Ca) with the electron configuration [Ar] 4s², and strontium (Sr) with the configuration [Kr] 5s². These elements are characterized by their reactivity and tendency to form +2 oxidation states.

What sub level are the valence electrons in group 2?
The valence electrons in group 2 elements are found in the s sublevel. These elements are known as alkaline earth metals and have 2 valence electrons, which occupy the s sublevel of their outermost electron shell.
What is the correct electron configuration for an electron configuration for an element with 5 elements in the 3d energy sublevel?
The correct electron configuration for an element with 5 electrons in the 3d energy sublevel is represented as ( \text{[Ar]} , 3d^5 ). This indicates that the element has a total of 23 electrons, placing it in the transition metals category, specifically manganese (Mn). The full electron configuration would be ( \text{[Ar]} , 4s^2 , 3d^5 ).
