Metals lose electrons to become stable because this takes less ___. energy
It takes (metals/nonmetals) less energy to gain electrons to become stable. nonmetals
Chloride ions have what charge? 1-
Aluminum ions have what oxidation number? 3+
Group 1 ions all have what charge? 1+
Group 2 ions all have what oxidation number? 2+
Bonds between a metal & non-metal are called ionic bonds
Metals tend to (gain / lose) electrons when they bond? lose
In ionic bonding, valence electrons are (shared/transferred)? transferred
Metals form ions that have this kind of charge positive
Nonmetals form ions that have this kind of charge negative
Nonmetals tend to (gain/lose) electrons to become stable gain
All atoms that gain or lose electrons do so in order to become this stable
The only stable elements as atoms are this group 18
The bond in an ionic bond is the attraction between (like/opposite) charges opposite
