Electron Configuration
The notation specific to the organization or arrangement of electrons within orbitals surrounding the nucleus.
What is electron configuration
The atom with the least reactivity of the elements on the periodic table.
What is Helium
The element that has an atomic number of 40
What is zirconium
The direction that electrons fill orbitals in order of their increasing energy on the periodic table
What is left to right
They occupy the energy levels of an atom.
What are electrons
The number of valence electrons aluminum (Al) has available for bonding
What is three
The size of the atom's radius when electrons are added to the outermost shell of a carbon atom
What is increase
Rb is classified into what group on the period table.
What is alkaili metals
Which group of elements are nonreactive
What are noble gases
The orbitals where the valence electrons where the valence electrons for Selenium are placed
What are the s and p orbitals
The element that has the electron configuration of 1s22s22p63s23p64s23d3
What is Vanadium
The electrons get farther from the nucleus so this trend occurs to the ionization energy going from the top to the bottom of a group.
What is decrease
The charge Chlorine will form in its ionic compounds
What is negative
What group of elements is the most reactive
What are alkali metals
The group of elements that has a stable number of electrons in their outer energy level.
What are noble gases
The number of valence electrons in cadmium (Cd)
What is two
The change in ionization energy that occurs between removing the first and second electrons from an atom because the ratio of the protons to electrons increases
What is increases
The term for when electron(s) are removed from the outermost shell of an atom thereby making the element to have a positive charge
What is cation
The man who is credited with creating the first periodic table
Who is Dmitri Mendeleev
The maximum number of electrons in the second energy level of an atom
What is eight
The noble gas notation for an element that has valence electrons in the 5s subshell.
What is Kr
The largest atomic radius out of the elements As, N, P and Sb
What is Sb
The most reactive element in the halogen family
What is fluorine
The work of Dmitri Mendeleev differed from that of John Newlands in the development of the periodic table in this way
What is Mendeleev predicted elements that would later be discovered.
The Lewis Dot diagrams are used to represent this
