Describe the periodic table
Displaying the elements in order of increasing atomic number and showing how periodicity of physical and chemical properties of the elements relates to atomic structure.
What is atomic radius?
Radius of an atom, i.e. the mean distance from the nucleus to the border of the outer orbital.
What is ionization energy?
Energy needed per mole to remove an electron(s) from an atom in the gaseous phase.
What is first ionization energy?
Energy needed per mole to remove the first electron from an atom in the gaseous phase.
What is electron affinity?
The energy released when an electron is attached to an atom or molecule to form a negative ion.
What is electronegativity?
A measure of the tendency of an atom in a molecule to attract bonding electrons.
