The elements in which the last electron enters the s-orbital of their outermost energy level are called s-block elements. The period of an element corresponds to the principal quantum number of the valence shell.. Touching the sensitive surface element will void warranty. Replies. Carbonates and Bicarbonates. Most have two, with several notable exceptions: elements may "steal" an electron from the outermost s block and relocate it to the d block in order to reach a filled or half-filled ($5$ of $10$ electrons) state in the d block. Elements in the d block are transition elements, and each posses one or two valence electrons in their respective s orbitals. Also known as transition metals, d-block elements are arranged from groups 3-12 and defined by their d-electron configuration, which we'll discuss later on in the lesson.
