Atomic radius - Answer✔️✔️-Half the distance between two identically bonded atoms
Ionic radius - Answer✔️✔️-The radii of the most commonly found ion of the element.
First Ionization Energy - Answer✔️✔️-The energy required to remove one electron from a
neutral atom of an element.
Electron Affinity - Answer✔️✔️-The energy change that occurs when an electron is
acquired by a neutral atom
Number of Valence Electrons - Answer✔️✔️-The electrons that are available to be lost,
gained, or shared in the formation of chemical compounds.
Melting point - Answer✔️✔️-The temperature at which a solid turns into a liquid.
Thermal Conductivity - Answer✔️✔️-The ability of a substance to conduct heat.
Electronegativity - Answer✔️✔️-The ability of an atom to pull the bonded electrons to
itself in a chemical compound.
Trend From Left to Right Across a Period (Atomic Radius) - Answer✔️✔️-Decrease
Trend From Left to Right Across a Period (Ionic Radius) - Answer✔️✔️-Decreases across
the metals and then gets much larger at the nonmetals and then decreases again.
