Ionic bonds occur when this
happens.
What is electrons are transferred
from one substance to another?
An ionic bond occurs when these
types of atoms react.
What are metals and nonmetals?
This is the generic name for the
type of ions nonmetals form
What are anions?
This is how the anion in a binary
ionic compound is named
What is the first part of the
element name with the last few
letters replaced with –ide (so it’s
pronounceable)?
This is the chemical formula and
name for the ionic compound
formed when Oxygen and
aluminum react.
What is Al2O3, called aluminum
oxide?
These are the particles found in
the nucleus of the atom.
What are protons and neutrons?
This is the name of the element
th
with 3 valence electrons in the 4
energy level.
What is Gallium?
This is the subatomic particle
responsible for all the elements
chemical characteristics.
What is the electron
This is what happens to the
reactivity of the metals as you go
down a group, and why it
happens.
What is Metals get more reactive,
because the valence electrons are
further from the nucleus and thus
easier to pluck off.
This is why reactivity increases
as you go left to right across a
period in the nonmetals
What is because of the increased
nuclear attraction between the
additional electrons and the
nucleus?
This is what is produced when an
atom loses or gains electrons.
What is an ION?
This is the name given to two or
more atoms of the same element
with different masses.
What are ISOTOPES?
This is the general name given to
the type of ion metals form.
What is a cation?
This is the number of neutrons in
an atom of Uranium-238.
What is 146 neutrons?
238 p+ and n – 92 p = 146 p+
This is what I would have if I
removed 3 neutrons, 3 electrons,
and 1 proton from the most
common isotope of Aluminum.
What is a +2 Magnesium-23
cation?
New atomic number = 13 – 1 = 12
New electrons = 13 – 3 = 10 (so 2 fewer e- than p+,
hence a +2 charge)
new neutrons = 14 – 3 = 11, so new mass number =
11 + 12 = 23
This is how many electrons fit in
the first energy level.
What is 2?
This is the name of the ionic form
of phosphorus.
What is phosphide (anion so
remove the last few letters and
add –ide)
This is why atoms gain or lose
electrons.
What is to gain a stable electron
configuration.
This is why hydrogen and helium
are often drawn separated from
the rest of the periodic table.
What is hydrogen is a nonmetal
and doesn’t have similar
properties to the other group 1A
elements (the alkali metals), and
helium has similar properties to
the rest of group 8A elements
(noble gases), but it has 2 valence
electrons, not 8?
This is an analogy you can use to
help remember reactivity trends on
the periodic table.
What are the metals are the salesmen, who want to sell
their inventory (valence electrons) to make their monthly
quota (become stable), the more they have to sell, the less
motivated they are to sell (because they don’t think they’ll
make their quota).
While the nonmetals are the collectors who want to by
products (valence electrons) to complete their collections
(filled valence shell). The closer they are to having a full
collection, the more motivated they are to buy that last one.
The rows are the experience level of each, the more
experienced the salesman, the more likely he will sell
(react), the more experienced the collector, the less likely
he will pay too much for the product (electron) and might
wait for a better deal (react less)
This is the number of valence
electron most of the elements
(except those in period 1) on the
periodic table want to have in
their highest energy level.
What is 8?
This is the name of the elements
that are located right around the
“stairs” on the periodic table.
What are the metalloids?
This is the general trend for how
easy it is to remove an electron
on the periodic table (both in a
group and in a period)
What is gets harder across a
period and gets easier down a
group?
This is the group name (not
group number) of the elements
that form -1 anions to become
stable.
What are the HALOGENS?
This is what the average atomic
mass represents.
What is the weighted average of
the masses of all the isotopes of
an element?
