(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

Octet rule
atoms are more stable when they have eight electrons in their outermost electron shell
Conduct heat and electricity, but not as well as metals
metaloids
what determines what the element is
The number of
protons in an atom
Valency of the "Carbon Group"
+4
-4
What is an atom?
the smallest unit of matter that retains all of the chemical properties of an element
Discovered the atomic nucleus
Ernest Rutherford
particle that has no charge
neutron
tells # of valence electrons = ?
Group #
electron configuration of atom in Period 4, Group 1
2,8,8,1
The largest category of elements
metals
Elements that are
poor conductors of both heat and electricity
non-metals
The electron configuration of an atom with 14 electrons
2,8,4
the atomic number
tells us the number of protons in an element's atom
holds
a maximum of two electrons
first energy level; innermost K- shell
elements within a period have the same number of ?
electron shells or orbitals
particle that has a negative charge
electron
Elements in Group 7 are called ?
Halogens
Why Group 0/8 elements are inert
Outer shell is filled
Where electrons with the lowest energy are found
electrons found closest to the nucleus
Horizontal rows in Periodic Table
Periods
Term for outer most shell of an atom
Valence shell
Valency
the ability of an atom
to react
(form chemical bonds) with other atoms
the center of the atom where most of the mass is located
nucleus
Atomic model that electron is a "cloud" around the nucleus
Quantum Mechanical model
luster
shiny
particle that has a positive charge
proton
increases from left to right across a Period
Atomic Number
discovered the electron; disproved atomic theory that assumed atoms were indivisible
J.J. Thompson
"plumb pudding" atomic model
negative particles floating within a
mass of diffuse positive charge
what atoms are mostly
empty space
atomic mass
total # of protons and neutrons in nucleus
An atom that has gained or lost an electron
Ion
a neutral atom
an atom with equal number of protons and electrons
said electrons could only orbit the nucleus in specific orbits or shells
Niels Bohr
atomos
Greek for "indivisible"
electron configuration of atom in Group 3, 2nd Period
2,3
The electron configuration of an atom with 15 electrons
2,8,5
early Greek to develop the idea that everything is composed entirely of various imperishable, indivisible elements called atoms.
Democritus
John Dalton
Developed the "Billiard Ball" atomic model
atomic mass unit
mass of one proton or neutron
Malleable
easily hammered into very thin sheets
Elements in Group 8 are called ?
Noble Gasses
how electron shells of an atom are filled
from the inside out
