Cation

A positively charged ion. When an atom loses an electron. Always smaller then original atom.

Ionization Energy

The energy required to remove an electron from an atom. The energy must be added because the atom is in a less stable (makes it postive). The larger the atom is, the easier its electrons are to remove.

Electron Affinity Periodic Trend

Trend Bottom to Top:Increases Trend Left to right:Increases Positive in the second and last group

Ionization Periodic Trend

Trend bottom to top:Increases Trend Left to right:Increases

Atomic Radius Periodic Trend

Trend moving right to left: increase Trend moving top to bottom:increase

Anion

When an atom gains an electron, it becomes negatively charged. Always larger then original atom.

Electronegativity

a measure of an atom's attraction for another atom's electrons.

Electronegativity Periodic Trend

increases up and to the right

Overall Reactivity

metals are the largest since they are the best electron givers. nonmetals are the smallest ones, the best electron takers.

Electron affinity

the energy change that occurs when an atom gains an electron. How much an atom wants an electron. It usually negative.

Ionization

the process by which an atom becomes an ion.

Effective nuclear charge

the pull that an electron "feels" from the nucleus.The increased attraction pulls the cloud in, making atoms smaller as we move from left to right across a period
