1.which of the following is true of the electrons in bohr model of the atom
they give off energy as they jump to a higher level
they exisit at specific energy levels
they cannont move from one orbital to another
they are equally close to the nucleus
2. What is true of valence electrons
they easily move from one orbital to another.
they are always the lowest energy electrons of the atom
they have diffculty moving from one ortital to another
they exist in the outer orbital
3. What must happen for an electron to move to a higher energy level?
the electron must collide with the nucleus
the electron must release energy throught fisson
the electron must transfer energy to another electron
the electron must gain energy
4. What must happen for an electron to fall to a lower energy level?
the electron must lose energy
the electron must collide witht the nuclues
the electron must transfer some energy to the nucleus
the electron must absorb light energy
5. Which scientist is credited with developing the orbital model of the atom?
JJ. Thomson
Niels Bohr
Ernest Rutherford
Democritus
