Why is there a distinct electron arrangement for each atom?
The electron arrangement of each atom is determined by the number of protons in the nucleus, which dictates the unique electronic structure and energy levels. This arrangement follows specific rules based on principles of quantum mechanics that govern how electrons distribute themselves around the nucleus. The electron configuration of an atom helps define its chemical properties and reactivity.

What is the relationship between the electron configuration of an element and the period in which that element appear in the periodic table?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
Which electron arrangement is that of a metallic element?
The electron arrangement of metallic elements typically involves one or two electrons in the outermost shell, which allows them to easily lose electrons and form positive ions. This electron arrangement gives metallic elements their characteristic ability to conduct electricity and heat well.
