QUESTIONS AND SOLUTIONS
CERTIFICATION REVIEW GRADED
A+
◉ atomic number = Answer: # of protons
◉ mass number = Answer: # of protons + neutrons
◉ the number of protons in a neutral atom will equal the Answer: # of
electrons
◉ how to find the correct number of neutrons Answer: mass number -
atomic number
◉ Forms of the same elements that differ in amount of neutrons
Answer: isotopes
◉ What particle, if lost from the nucleus, would NOT cause a change in
the atomic number? Answer: a neutron because it has no charge
◉ When alpha particles were shot at a metal foil target, most passed
through without deflections, while others deflected at large angles.
,What did this suggest to Rutherford? Answer: that the atoms of the
metal were mostly empty space, while the nucleus consisted of most of
the mass which included highly condensed positive particles (which
caused the deflection).
◉ An atom has a valence shell configuration of 1s1. To which group of
elements on the periodic table does it belong? Answer: IA
alkali metals
◉ electromagnetic spectrum Answer:
◉ The greater the wavelength of a photon..? Answer: the lower its
frequency
◉ The greater the frequency of a photon...? Answer: the shorter its
wavelength
◉ Light energy formula Answer:
◉ What does C in the light energy formula represent? Answer:
◉ Give the ground-state electron configuration of an atom in the
second period Answer: 1s2 2s1
, ◉ Electrons configuration rule that states electrons do not pair until
they have to. (put one electrons in each electron domain then pair up)
Answer: Hund's rule
◉ An experimental phenomena associated with atoms having unpaired
electrons - which states such substances are attracted to magnetic
fields Answer: Paramagnetism
◉ Which drop in energy level results in the greatest emission of
energy? Answer: n=2 to n=1
◉ quantum numbers Answer:
◉ What do the 4 quantum numbers stand for? Answer: n = energy
level
l = (n-1)
ml -l to l
mn 1/2 or -1/2 (spin)
◉ List the quantum numbers for the s, p, d, and f orbitals Answer: s
1,0,0
p 2, 1, -1-0-1
d 3, 2, -2--1-0-1-2
f 4, 3 -3--2--1-0-1-2-3
