Atomic Structure
This subatomic particle has a negative charge.
What is an electron?
As you move from left to right across a period in the periodic table, atomic radius generally does this.
What is decrease?
This scientist's wave equation revolutionized our understanding of atomic structure by describing electrons as having both particle and wave properties, and his equation is fundamental to quantum mechanics.
Who is Erwin Schrödinger?
Atoms of the same element with different numbers of neutrons.
What are isotopes?
This property measures an atom's ability to attract electrons in a chemical bond.
What is electronegativity?
The weighted average of the masses of all naturally occurring isotopes of an element.
What is the relative atomic mass (or atomic weight)?
The element with the highest electronegativity in the periodic table.
What is fluorine?
This experiment by Ernest Rutherford led to the discovery of the nucleus.
What is the gold foil experiment?
This periodic trend increases as you move up a group and from left to right across a period.
What is ionization energy?
This principle states that no two electrons in an atom can have the same four quantum numbers.
What is the Pauli Exclusion Principle?
This term describes the shielding effect of inner electrons that reduces the nuclear attraction on valence electrons.
What is electron shielding (or screening)?
