organization of the periodic table:
● The classic Periodic Table organizes the
chemical elements according to the number of
protons that each has in its atomic nucleus. The
Periodic Table of the Elements arranges all of
the known elements in an informative array.
3
Families and properties of the families:
● The Periodic Table: Families and Periods. In the
periodic table of elements, there are seven
horizontal rows of elements called periods. The
vertical columns of elements are called groups,
or families.
4
Metals
● a solid material that is typically hard, shiny,
malleable, fusible, and ductile, with good
electrical and thermal conductivity e.g., iron,
gold, silver, copper, and aluminum, and alloys
such as brass and steel.
5
Nonmetals
● :an element or substance that is not a
metal.on-metals are not able to conduct
electricity or heat very well. As opposed to
metals, non-metallic elements are very brittle,
and cannot be rolled into wires or pounded into
sheets.
6
Metalloids
● ,an element e.g., germanium or silicon whose
properties are intermediate between those of
metals and solid nonmetals. They are electrical
semiconductors
7
Periodic law
● ,originally the statement that the chemical and
physical properties of the elements recur
periodically when the elements are arranged in
the order of their atomic weights.
8
Noble gas electron configurations
● The basis of all chemical reactions is the
tendency of chemical elements to acquire
stability.
9
Periodic table trends:
Periodic trends, arising from the arrangement of
the periodic table, provide chemists with an
invaluable tool to quickly predict an element's
properties.
10
Atomic radius
● of a chemical element is a measure of the size
of its atoms, usually the mean or typical distance
from the center of the nucleus to the boundary of
the surrounding cloud of electrons.
11
Ionic charges
● On the Periodic Table metals found on the left
of the table will be positive
12
Ionization energy:
● The first ionisation energy is the energy required
to remove the most loosely held electron from
one mole of gaseous atoms to produce 1 mole of
gaseous ions each with a charge of 1+.
13
Electro-negativity
● Electronegativity is a measure of the tendency of
an atom to attract a bonding pair of electrons
14
Octet rule
● The octet rule is a chemical rule of thumb that
reflects observation that atoms of main-group
elements tend to combine in such a way that
each atom has eight electrons in its valence
shell, giving it the same electronic configuration
as a noble gas.
15
Valence electrons
● a valence electron is an electron that is
associated with an atom, and that can participate
in the formation of a chemical bond; in a single
covalent bond, both atoms in the bond contribute
one valence electron in order to form a shared
pair.

How was the original Periodic Table
organized and compare it to today’s
version, include discussion of Periodic
Law?
The Russian chemist Dmitri Mendeleev was the
first scientist to make a periodic table similar to the
one used today citation needed. Mendeleev arranged the
elements by atomic mass, corresponding to relative
molar mass.
