Periodic Table
what is purple
particle that has a positive charge
what is a proton
chemical bond formed when two atoms share one or more valence electrons
what is a covalent bond
the attraction between positively and negatively charged ions in an ionic compound
diagram that shows how # of valence electrons of each atom and how they are going to bond
what is an electron dot diagram
rows on the periodic table
what are periods
particle that has a negative charge
what is an electron
number of valence electrons an atom should have after sharing
8 (2 if hydrogen)
an atom that is no longer electrically neutral because it has lost or gained valence electrons
what is an ion
# of side on a hexagon

increasing by 1, left to right- this also tells you how many protons and electrons an element has
what is the atomic number
2 particles that make up an atom of a nucleus
what is the proton and neutron
a molecule that has a partial positive and partial negative end because of unequal sharing of electrons
what is a polar molecule
Name of major interstate that runs North to South in Oregon
what is I-5
a small number after a chemical symbol that represents the number of atoms of each element in the compound
What is a subscript
how to solve for number of neutrons an atom has
subtract the atomic number from the atomic mass, round to the nearest whole number
Oregon state bird or tree
what is the Meadowlark or the Douglas Fir
a group of atoms held together by covalent bonding that acts as an independent unit
what is a molecule
group that does not bond because already stable with 8 valence electrons
what is noble gases
a group of chemical symbols and numbers that represent the elements and the number of atoms of each element that make up a compound
what is a chemical formula
