metals tend to lose/gain e- to become noble gases
lose
across a period, metallic character inc/dec
dec
effective nucelar charge (Zeff = Z-core e-) across a period
increases since more protons but not that many more core (more valence)
down a group, metallic character
up bc more e- = farther away from nucleus and easier to grab since less of a pull from nucleus
effective nucelar charge (Zeff = Z-core e-) down a group
dec bc both new protons and core e- are added, but the new valence e- have a bigger distance that decrease the overall force from nucleus
where are the valence e- most strongly attracted to nucleus/where is the biggest effective nuclear charge?
