who discovered that atoms have a positively charged mass in the center, discovered the nucleus
(a)
who discovered that electrons orbit around the nucleus (based on their mass)
(a)
who discovered that electrons move in cloud like approximations around the nucleus
(a)
what model did thomson develop
(a)
what model did rutherford develop
(a)
what model did bohr develop
(a)
what model did schrodinger develop
(a)
how did thomson come to his conclusion
a cathoray tube, found + and - charges when some deflected the negative coil
the gold foil experiment, some of the + particles (that he fired) deflected, and he found the nucleus
used rutherford and max plancks work to combine and cross reference
past observations, mathematical equations, and physical experimentation

the gold foil experiment, some + particles (that he fired) deflected, and he found the nucleus
used rutherford and max planck work to combine and cross reference
past observations, mathematical equations, and physical experimentation

(a)
what is the charge, mass, and location of a neutron
(a)
what is the charge, mass, and location of an electron
(a)
what subatomic particle determines an element's identity
proton
neutron
electrons
idktron
each element on the periodic table has a different number of
(a)
what is an ion
an atom with one or more electrical charges (+ or -)
an atom that has gone from + to -
an atom that has filled up it's valence electrons and now has to expand for extra space
an atom with only one electrical charge (+ or -)
what is an isotope
an element with a different number of neutrons and mass number than shown on the periodic table
another word for ion
an element without an atomic mass
an element without an atomic number and number of neutrons than shown on the periodic table
what changes in an isotope
(a)
what stays constant in an isotope
(a)
how to find the average atomic mass of an element
(#)(percentage)+(#)(percentage) and so on
add all the percentages
(#)(percentage)/(#)(percentage) and so on
multiply all the numbers and then add the total percentage to the product
what is fission
the splitting of a nucleus (atom) into smaller parts
the combining of nuclei (atoms) to form a nucleus (atom) of more mass
what is fusion
the splitting of a nucleus (atom) into smaller parts
the combining of nuclei (atoms) to form a nucleus (atom) of more mass
how does nuclear fusion pertain to the sun
the sun's temperatures cause hydrogen atom's nuclei to fuse together and create helium
the sun’s molecules fuse together to create heat and light that it releases
the suns protons and neutrons fuse together to form bigger atoms that release light and heat energy
ground state
lower energy levels
higher energy levels
excited state
lower energy levels
higher energy levels
based on an electrons state (ground/excited) it will release energy in the form of
(a)
which is a valid example of electronic configuration
1s^2,2s^2,2p^3
1d,2p^6,3k^3
232,2ph4,NeCl
1s^4,2d^10,3p^5
in the s block, there are _____ orbital(s) w/_____ electrons
(a)
in the p block, there are _____ orbital(s) w/_____ electrons
(a)
in the d block, there are _____ orbital(s) w/_____ electrons
(a)
in the f block, there are _____ orbital(s) w/_____ electrons
(a)
who are the men that came up with the configuration rules
Aufbau
Pauli
Hunds
Jeter
what is aufbau's configuration rule
electrons occupy orbitals of lower energy levels first
electrons pair up and then fill orbitals
electrons must be of higher energy before becoming one of lower energy
a hyphen notation of an isotope element is
the name of the element, a dash, and the atomic mass
the name of the element, a dash, and the atomic number
the nuclear symbol of an isotope looks like
the periodic table name of the element, with the atomic number on it's bottom right and mass number on it's top right
the periodic table name of the element, with the mass number on it's bottom right and atomic number on it's top right
atomic mass/ mass number =
protons+neutrons
neutrons+electrons
electrons+protons
protons+neutrons+electrons

why was democritus wrong
he said atoms were indivisible
he said atoms have electrons
he said atoms have a nucleus
he said atoms taste like plum pudding
