Moles and Molar Mass
what is avogadro's number
what is 6.022 x 10^23
What is the mass of one proton
what is one amu
What number of protons in an atom's nucleus; the element's "address" on the periodic table
what is atomic number
what is binding energy
what it he energy needed to remove an electron
what is atomic radius affect on the periodic trend, moving from left to right
what is decrease
Define molar mass
what is the mass of neutron
what is one amu
what is the sum of an atoms protons and neutrons
what is mass number
what is the difference between core and valence electrons in terms of binding energy
binding energy is core electron are higher than the ones in valence electrons
what is ionization energy affect on the periodic trend, moving from left to right
what is increase
Convert moles to mass using moles and molar mass
what is moles x molar mass = mass
what is the mass of electron
what is 1/1836 amu or negligible
what are the three types of particles found in an atom
what is proton, neutron, and electron
In a spectra, what does a high binding energy mean in terms of distence to the nucleus
what is closer to the nucleus the higher the binding energy
what is electronegativity affect on the periodic trend, moving from left to right
what is increase
convert mass to particles
mass / molar mass x 6.022 x 10^23 = particles
how to calculate average atomic mass
Average Atomic Mass (amu) = (atomic mass of Isotope * % of abundance)/100
the sume of the products of each isotope's mass mutipled by their percentages
what is the electron on the outermost energy level called
what is valence electrons
what laws explain the why the closer an electron is the higher the binding energy.
what is coulomb's law
what is the difference between electron affinity and electronegativity
what is electronegativity is the ability for an atom to attract an electron while electron affinity is the energy change that an atom experience when it gains an electron.

what is 35.5 amu
what ground state element is this? 1s22s22p63s23p2
what is silicon
what did the Photoelectron spectroscopy prove what model was limited
what is the bohr's model
explain why noble gases have zero or really low electonegativity
what is becuase their full outer shell makes them incapable to attracting additional electrons
