to form a solution by mixing evenly
not linked to any specific atom or ion, able to move about within the structure
prevent electricity or heat from passing through (related word: insulation)
the force that gives an atom the ability to attract and hold electrons.
A mixture of two or more metals
Capable of being dissolved
A substance that is dissolved in a solution.
A liquid substance capable of dissolving other substances
ionic bonds
Bond formed by a transfer of electron(s)
covalent bonds
bond in which atoms share electrons
metallic bonds
valence electrons shared among all atoms; "sea of electrons"
(adj) able to be bent, shaped, or can be hammered flat
conductor (n)
A material that allows heat and electricity to pass through it.
conductive (adj)
having the quality or power of allowing heat or electricity to pass through it
melting point
The temperature at which a solid becomes a liquid
boiling point
The temperature at which a substance changes from a liquid to a gas.
easily set on fire
The ability of an object to transfer heat or electricity to another object.
Any chemical substance that, in small amounts, alters biological or cognitive processes or both; aka pharmaceutical
breaks or shatters easily
A term used to describe a material that can be pulled out into a long wire.
chemical bonds
an attraction between atoms in order to create compounds made of two or more atoms
octet rule
Atoms form bonds in order for each atom to have a complete outer shell, and to become stable and 'happy'
Metals + Nonmetals
Ionic compounds are made of
Metallic compounds are made of
Covalent compounds are made of
example(s) of ionic compounds
Water and Oxygen Gas
example(s) of covalent compounds
example(s) of metallic compounds
Rules for both ionic and covalent bonds
1. First element is written first with the full name.
2. The second element has the ending -ide
chemical change
means bonds bond or break to form new substances
pure substance
Matter that always has exactly the same composition
a combination of two or more substances that are not chemically combined
a substance made up of atoms of two or more different elements joined by chemical bonds
A pure substance made of only one kind of atom
macroscopic level
matter large enough to be seen, measured and handled
molecular level
what you can't see, but can imagine
valence electrons
electrons in the outer shell of an atom
1st ring
2 electrons
2nd ring
8 electrons
electrically charged atoms that have gained or lost electrons.
Positive ion, Lose their valence electrons, From atoms with less than 4 valence electrons
Negative ion, Gain valence electrons, From atoms with more than 4 valence electrons
octet rule
in forming compounds, atoms tend to achieve the electron configuration of a noble gas
valence shells
outermost shell of an atom
