검증된 단계별 안내1
Identify the groups in question: Groups 1 and 2 in the periodic table are known as the alkali metals and alkaline earth metals, respectively.
Recall the electron configuration pattern: Electrons fill orbitals in a specific order based on energy levels, starting with the lowest energy orbitals.
Understand the orbital types: The main types of orbitals are s, p, d, and f, each with different shapes and capacities for electrons.
Recognize that for Groups 1 and 2, the outermost electrons are added to the s orbital of their highest principal energy level (outermost shell).
Conclude that the electrons for elements in Groups 1 and 2 enter the s orbitals in their outermost shell, which is why these groups are often called the s-block elements.
