Chem Exam Ch.4

Final Exam

an element with 8 elecrons in its highest main energy level is a noble gas
the emission of electrons from metals that have absorbed photons is called the photoelectric effect
the region outside the nucleus where an electron can most probably be found is the electron cloud
how many quantum numbers are deeded to describe the energy state of an electron 4
the wave model of light did not explain the photoelectric effect
which group are the noble gases 18
what is the total number fo electrons needed to fill the fist two main energy levels 10
the atomic sublevel with the next highest energy after 4p is 5s
becasue excited hydrogen atoms always produce the same line emission spectrum, scientists concluded that hydrogen released photons of only certain energy
the number of orbitals for the d sublevel is 5
