Atom Vocabulary G Mass number - sum of the protons and neutrons in the nucleus. G Atomic mass - the average mass of all isotopes of an element. G Atomic number - the number of protons in the nucleus. G Isotopes - atoms with the same number of protons and a different number of neutrons. Such as Carbon 12, 13, and 14. G Mass number - sum of the protons and neutrons in the nucleus.

Metals G Physical Properties G Luster - shininess G Malleable-hammered or rolled into flat sheets G Ductile-pulled out or drawn into a long wire G Conductivity-ability to transfer heat or electricity G Color-produced when heated G Magnetic-attracted to a magnet G Physical Properties G Luster - shininess G Malleable-hammered or rolled into flat sheets G Ductile-pulled out or drawn into a long wire G Conductivity-ability to transfer heat or electricity G Color-produced when heated G Magnetic-attracted to a magnet

Metals Continued G Chemical Properties G Reactivity-ease and speed with which an element combines, or reacts with other elements and compounds G Corrosion-the destruction of a metal (rust) G Chemical Properties G Reactivity-ease and speed with which an element combines, or reacts with other elements and compounds G Corrosion-the destruction of a metal (rust)

Metal Family Names G Family 1 - Alkali Metals (react with other elements by losing one electron) ex. Na and K G Family 2 - Alkaline Earth Metals (react with other elements by losing two electrons) ex. Mg and Ca G Families Transition Metals (good conductors of electricity) ex. Fe, Au, Ag, Cu G Family 1 - Alkali Metals (react with other elements by losing one electron) ex. Na and K G Family 2 - Alkaline Earth Metals (react with other elements by losing two electrons) ex. Mg and Ca G Families Transition Metals (good conductors of electricity) ex. Fe, Au, Ag, Cu

Family Names Continued G Families Metals in Mixed Groups - not as reactive as those elements on the left side of the periodic table G Lanthanides and Actinides - found at the bottom of the periodic table part of period 6 and 7 respectively G Families Metals in Mixed Groups - not as reactive as those elements on the left side of the periodic table G Lanthanides and Actinides - found at the bottom of the periodic table part of period 6 and 7 respectively

Nonmetals G Properties: G Poor conductors G Brittle - breaks apart easily G Dull G Most are gases G Reactive with other elements G Properties: G Poor conductors G Brittle - breaks apart easily G Dull G Most are gases G Reactive with other elements

Nonmetal Family Names G Family 14 - Carbon Family (can gain lose or share 4 electrons when reacting with other elements) ex. Carbon is contained in anything living or was once living G Family 15 - Nitrogen Family (can gain or share 3 electrons when reacting) ex. Nitrogen - makes up 78% of the air you breathe G Family 16 - Oxygen Family (can gain or share 2 electrons) Oxygen makes up 21% of the air you breathe G Family 14 - Carbon Family (can gain lose or share 4 electrons when reacting with other elements) ex. Carbon is contained in anything living or was once living G Family 15 - Nitrogen Family (can gain or share 3 electrons when reacting) ex. Nitrogen - makes up 78% of the air you breathe G Family 16 - Oxygen Family (can gain or share 2 electrons) Oxygen makes up 21% of the air you breathe

Nonmetal Families Continued G Family 17 - The Halogen Family (can gain or share 1 electron when reacting) **All of the halogens are very reactive ex. F, Cl, Br, I, and At G Family 18 - The Noble Gases (do not ordinarily form compounds because atoms of noble gases do not usually gain, lose, or share electrons) ex: He, Ne, Ar, Kr, Xe, and Rn G Family 17 - The Halogen Family (can gain or share 1 electron when reacting) **All of the halogens are very reactive ex.

The Metalloids G Metalloids have some characteristics of both metals and nonmetals. G The most useful property of the metalloids is their varying ability to conduct electricity. G Semiconductors - substances that can conduct electricity under some conditions but not under other conditions G Ex. Si, Ge, As G Metalloids have some characteristics of both metals and nonmetals. G The most useful property of the metalloids is their varying ability to conduct electricity. G Semiconductors - substances that can conduct electricity under some conditions but not under other conditions G Ex. Si, Ge, As

Element Facts G Iron (Fe) - the blood element G Potassium (K) - found in bananas G Calcium (Ca) - necessary for strong teeth and bones G Lead (Pb) - once used in gasoline, pencils and paint G Aluminum (Al) - lightweight metal used in house siding, beverage cans and airplane bodies. G Hydrogen (H) - makes up over 90% of the universe G Iron (Fe) - the blood element G Potassium (K) - found in bananas G Calcium (Ca) - necessary for strong teeth and bones G Lead (Pb) - once used in gasoline, pencils and paint G Aluminum (Al) - lightweight metal used in house siding, beverage cans and airplane bodies.
