What was Bohr's basic proposal about the atom?
An electron remains in a fixed position in the space around the nucleus.
An electron is found in a specific circular path, or orbit, around the nucleus.
An electron oscillates, or moves back and forth, within one small region of space in the atom.
An electron readily exchanges position with either a proton or a neutron.

How does the quantum mechanical model differ from the Bohr model in the way it describes the arrangement of electrons in atoms?
The quantum mechanical model describes electrons as moving anywhere in the atom, not specific circular orbits.
The quantum mechanical model describes electrons as moving through specific orbits, and not staying in one place.
The quantum mechanical model places electrons in fixed positions, not moving through specific orbits or orbitals.
The quantum mechanical model describes electrons as moving through cloud-like orbitals, not specific circular orbits.

The isotopes of hydrogen-1 and hydrogen-2 make up nearly all of the hydrogen found in nature. The mass of hydrogen-1 is 1.0078 amu and the mass of hydrogen-2 is 2.0141 amu. Becuase the average atomic mass of hydrogen is 1.0079 amu what can be concluded about the 2 isotopes of hydrogen?
Hydrogen-1 is by far the more abundant isotope.
Hydrogen-2 is by far the more abundant isotope.
Hydrogen-1 and hydrogen-2 are about equally abundant.
The isotope hydrogen-3 does not exist in nature.
Answer explanation
Since the average atomic mass is closer in value to the mass of hydrogen-1, we can assume that it is more abundant relative to hydrogen-2.

The atomic mass of oxygen is 15.999 amu. What does this value equal?
The mass of a randomly chosen oxygen atom
The mass of every oxygen atom
The mass of an atom of the most common oxygen isotope
The weighted average mass of oxygen atoms in nature
Answer explanation
The weighted average is determined by the relative abundance of each oxygen atom and isotopes.

An element has an atomic number of 76. The number of protons and electrons in a neutral atom of the element are ____.
152 protons and 76 electrons
76 protons and 0 electrons
38 protons and 38 electrons
76 protons and 76 electrons
Answer explanation
The atomic number also specifies the amount of protons within an element's atom. For a Neutral (charge = 0) atom, the amount of protons and electrons will be equal.
