The repeating patterns of chemical and physical properties through the periodic table is called (a) .
Thanks to a discovery made by _______________, the elements in the periodic table are arranged in order of atomic number.
Glenn Seaborg
William Ramsay
Hennig Brand
Henry Moseley
Which of the following was Gilbert Newton Lewis’ major contribution to developing the periodic table?
noble gasses
law of triads
valence bond theory
discovery of phosphorus
Periodicity in the periodic table is caused by:
level of reactivity
size of atomic radius
pattern of valence electrons
atomic number
“Look like metals, but mostly behave like nonmetals, are shiny and brittle…” best describes what category of elements?
(a)
Which group of elements has 4 valence electrons? (just type in the number)
(a)
The actinide elements are best described as:
low densities, soft and easy to cut, and highly reactive with water
highly reactive with alkili metals and alkaline earth metals, and toxic in elemental form
like transition metals, but radioactive; the heaviest are extremely unstable and do not occur naturally
high densities, very hard, malleable and excellent conductors of heat and electricity
Electron affinity is:
the amount of energy released or spent when an electron is added to a neutral atom
the set of chemical properties that are associated with the elements classified as metals
a way of measuring how likely it is that an atom will gain an electron
the tendency of an atom to attract bonding electrons
“The set of chemical properties that are associated with the elements classified as metals in the periodic table” best describes which periodic trend?
(a)
How many valence electrons do sulfur, tellurium and polonium each have?
(a)
All the alkali metals have electrons filling which orbitals?
s
p
d
f
The metalloids are found _______________________________.
groups 13-16
between the post-transition metals and non-metals
most of group 16
in the f-block portion of period 6
“Increasing down each group and increasing to the right from group 17 to group 15, dropping down, and then increasing again from group 13 to group 1,” best describes which periodic trend?
(a)
Which group is most likely to have the highest boiling points?
1
17
18
7
