Element name
usually ends with- ide after it becomes an anion.
Chemical formulas
are written based on the ratio of the elements.
noble gas…
In forming compounds, atoms tend to achieve the electron configuration of a(n) (valence electron of 8)
Protons
are located in the center and electrons are on the outside… only electrons can be taken away.
atom
A(n) with positive or negative charge is called an ION.
Elements WITHOUT charge
are called ATOMS.
Metal atoms
tend to lose, gaining a complete octet in the next lowest energy level, while nonmetals tend to gain electrons to achieve a complete octet.
Ionic Bonds
: When positive protons are attracted to negative electrons.
Chemical Bonds
: The force that holds two atoms together.
negative charge
The particles that make up atoms have either positive or .
Ionic compounds
can conduct and electric current when melted or dissolved in water because their ions are free to move (electrolytes)
Ionic bonds
are formed between two ions by the TRANSFER of electrons.
