The Periodic Table of Elements

The property of an atom that measures the strength of the nucleus' pull on the electrons of other atoms bonded to it.

• Ionization energy

• Electronegativity

• Metallicity

• Nonmetallicity

The property of a particular kind of atom that relates to how easy it can remove its valence electron/s.

• ionization energy

• electronegativity

• metallicity

• non-metallicity

The kind of atom that is mostly located at the upper right corner of the periodic table of elements.

• non metals

• transition metals

• metalloids

• representative metals

The kind of atoms that can form colored compounds and are located at the center of the periodic table of elements.

• non metals

• representative metals

• transition metals

• metalloids

The kind of atoms which would likely have the highest ionization energies, highest electronegativities, and greater positive (effective) nuclear charge because of its smaller size within a Period in the periodic table of elements.

• non metals

• representative metals

• transition metals

• metalloids
