|
Made up of the alkali metals.
|
IA
|
|
|
|
In reactions, these elements all tend to lose a single electron.
|
IA
|
|
|
|
This family contains some important elements, such as Na and K, which play an important role in the chemistry of the body and are commonly found in salts.
|
IA
|
|
|
|
Made up of the alkaline earth metals.
|
IIA
|
|
|
|
All of these elements tend to lose two electrons.
|
IIA
|
|
|
|
Ca is an important member of this family.
|
IIA
|
|
|
|
This family is made up of the halogens.
|
VIIA
|
|
|
|
Members of this family tend to gain a single electron in reactions.
|
VIIA
|
|
|
|
Important members of this family include Cl, used in making table salt and bleach, and I,. (Tincture of Iodine is used as a disinfectant.)
|
VIIA
|
|
|
|
This family is made up of the Noble Gases.
|
VIIIA
|
|
|
|
Members of this family are VERY unreactive.
|
VIIIA
|
|
|
|
For a long time, this family was called the inert gases because people thought these elements wouldn't react at all.
|
VIIIA
|
|
|
|
A scientist named Neil Bartlett showed that at least some members of this family could be reacted, but only under very special circumstances.
|
VIIIA
|
|
|
|
Members of this group include: Li, Na, K, Rb (Rubidium), Cs (Cesium), and Fr (Francium).
|
IA
|
|
|
|
Members of this group include: Be (Berylium), Mg, Ca, Sr (Strontium), Ba (Barium), and Ra (Radium).
|
IIA
|
|
|
|
Members of this group include: F, Cl, Br (Bromine), I, At (Astatine).
|
VIIA
|
|
|
|
Members of this group include: He, Ne (Neon), Ar (Argon), Kr (Krypton), Xe (Xenon), and Rn (Radon).
|
VIIIA
|
|
|
|
The 7 horizontal rows of elements are called:
|
periods.
|
|
|
|
Atomic #s increase from:
|
left to right.
|
|
|
|
Members of a (period or family) have chemical propeties that are similar.
|
family
|
|
|
|
Electron configuration show that some similarities amoung each group (family) of elements are in terms of their:
|
valence electrons.`
|
Valence electrons are the s and p electrons in the outermost energy level of an atom.
|
|
|
All elements in IA group have one valence electron in the ___ orbital.
|
s
|
|
|
|
The IIA elementseach have ____ valence electrons in the ___ orbital.
|
2, s
|
|
|
|
The elements of VIIA each have 7 valence electrons in which orbitals?
|
s and p orbitals
|
d orbitals DON"T COUNT
|
|
|
Members of VIIIA each have 8 valence electrons, making their valence orbitals:
|
filled.
|
|
|
|
Easy way to remember the # of valence electrons in each family?
|
IA has 1
IIA has 2 VIIA has 7 VIIIA has 8 |
|
|
|
Why are the members of VIIIA extremely hard to react?
|
Because their valence (outermost) energy level is full.
|
They are stable (satisfied) with a filled (complete) valence energy level.
They don't easily lose, gain, or share electrons. |
|
|
Which family satisfies the octet rule?
|
VIIIA
|
|
|
|
What is the driving force in chemical bonding?
|
Achieving stability by having a filled valence shell.
|
|
|
|
Elements found in the middle of the periodic table, labeled with a Roman numeral and a "B", are commonly called:
|
the transition metals.
|
|
|
|
These elements are progressively filling the d orbital.
|
Transitional metals.
|
The progressively added electrons fill the d orbitals.
The number of electrons in the s and p orbitals are not changing. |
|
|
Name the two groups of elements that are not in the main body of the periodic table?
|
Lanthanides and Actinides
|
Clasified as the Inner Transition Metals.
Progressively filling the f orbitals much the same way that the electrons of the transition metals fill the d orbitals. |
|
|
The Lanthanide and Actinide groups of elments are called:
|
Inner Transition Metals
|
|
