Q

Tamaño Iónico

A

el tamaño de un atómo, despues de ganar or perder un electrón (tamaño de un ión)
(cations are smaller than their neutral parent, whereas anions are larger than their neutral parent)
electrons repel each other, adding an electron makes the atom bigger.

Q

Energía de Ionización

A

la energía necesaria para quitar un electron de valencia, de un atómo. (la más niveles de energía un atómo tienen, la mas facíl es para quitar un atómo, entonces menos EI)

Q

Electron affinity

A

how much an atom wants to gain an electron (atoms with 1 ve want to lose rather than gain, so less electron affinity, whereas atoms with 7 ve want to gain, so greater electron affinity)
