Terms in this set (20)
An ion with a negative charge. Formed by gaining electrons
An ion with a positive charge. Formed by losing electrons.
They normally lose electrons during chemical reactions. Usually, form positive ions.
They normally gain electrons during chemical reactions. Usually form negative ions.
An atom that has an electrical charge.
The force that holds atoms together.
a chemical bond between oppositely charged ions.
Electron dot diagram (aka Lewis structures)
A shorthand representation of the valence electrons in an atom.
Chemical symbols that show the ratio and amount of elements in a compound.
How to write the formula for an ionic compound:
write the symbol for your metal first, then your nonmetal second.
Naming ionic compounds
The name of the metal comes first, followed by the name of the nonmetal, changing the nonmetal's ending to "ide".
Ionic compounds will conduct electricity
when dissolved in a liquid
metal being hammered into a thin sheet
metal that can be drawn into a thin wire
outermost electrons which will determine bonding.
Atoms gain or lose electrons to get a full outermost energy level.
a chemical bond that results from the sharing of electrons
tell the amount of atoms in a compound
elements that covalently bond with themselves to form a molecule
