(19 cards)
one of the elements in Group 1 of the periodic table
Alkali Metals
one of the elements in Group 2 of the periodic table
Alkaline Earth Metals
the combining of atoms to form molecules or ionic compounds
Chemical Bonding
a change that occurs when one or more substances change into an entirely new substance with different properties
Chemical Change
a bond formed to share one or more pairs of electrons
Covalent Bond
a vertical column of elements on the periodic table; elements in a group share chemical properties
Group
one of the elements of Group 17 on the periodic table;
_______ combine with most metals to form salts
Halogens
a bond that forms when electrons are transferred from 1 atom to another, which results in a positive ion and a negative ion
Ionic Bond
a property of matter that describes
A substance’s ability to participate in chemical reactions.
Chemical Property
a charged particle that forms when an atom or group of atoms gains or loses one or more electrons
lons
an element that is shiny and that conducts heat and electricity well.
Metal
elements that have properties of both metals and nonmetals.
Metalloid
one of the elements of Group 18 of the periodic table; noble gases are unreactive.
Noble gas
an element that conducts heat and electricity poorly.
Nonmetal
In chemistry, a horizontal row of elements in the periodic table
Period
the law that states that the repeating chemical and physical properties of elements change periodically with the atomic numbers of the elements.
Periodic law
a change of matter from one form to another without a change in chemical properties.
Physical change
a characteristic of a substance that does not involve a chemical change, such as density, color, or hardness.
Physical property
an electron that is found in the outermost shell of an atom that determines the atom’s chemical property.
Valence electron
