Ion Formation (Chapter 6, Lesson 1) Flashcards
Chemical Bond
Force that holds two atoms together
Cation
a positively charged ion
Anion
a negatively charged ion
Electron affinity (EA)
a term used to describe how much attraction an atom has for electrons.
Metal atoms are reactive because…
they lose valence electrons easily.
Noble gases have…
high ionization energies and low electron affinities.
When does a positive ion form?
When it loses one or more valence electrons. (to attain a noble gas configuration)
What can be used to illustrate formation of bonds?
Electron-dot structures
What charges do transition metals commonly form?
2+ or 3+
(but can form greater than 3+)
Pseudo-noble gas configurations
Other relatively stable electron arrangements
What suffix can be added to label an anion?
-ide
to the root name of the element
Nonmetals can..
…easily gain electrons to attain a stable outer electron configuration
When does a negative ion form?
When it gains one or more valence electrons
What can some nonmetals do?
They can lose or gain other numbers of electrons to form an octet.
