FAMILIES
This family is in Group 18 and never reacts with anything.
NOBLE GASES
The number of valence electrons for any element in Group 1.
This family is the MOST reactive because they have only 1 valence electron to lose.
ALKALI METALS
A cation has this type of electrical charge (positive or negative?).
positive
An anion has this type of electrical charge (positive or negative?).
negative
This family is in Group 1 and reacts violently with water.
ALKALI METALS
The number of valence electrons for any element in Group 2.
2
This family is very reactive because they need to gain 1 electron to fill their outer shell.
halogens
When an atom loses an electron, it becomes this type of ion.
cation
When an atom gains an electron, it becomes this type of ion.
anion
This family is in Group 17 and is known as "salt formers."
HALOGENS
The number of valence electrons for any element in Group 17.
7
This is why noble gases are not reactive at all.
because their outer shell is full
This side of the periodic table (left or right?) produces cations.
left side
This side of the periodic table (left or right?) produces anions.
right side
This family is in Group 2 – less reactive than Group 1, but still very reactive.
ALKALINE EARTH METALS
The number of valence electrons for any element in Group 18 (except helium).
These two families react violently with each other to form salts.
alkali metals and halogens
What type of elements become cations – metals or nonmetals?
metals
What type of elements become anions – metals or nonmetals?
nonmetals
This family has a full outer shell of electrons, making them inert.
NOBLE GASES
This term describes the electrons in the outermost shell of an atom.
VALENCE ELECTRONS
True or false: Alkaline earth metals are more reactive than alkali metals.
false (They are less reactive.)
If an atom has 1 valence electron and loses it, the charge of the resulting cation.
1+ (or positive one)
If an atom has 7 valence electrons and gains 1 electron, the charge of the resulting anion.
1- (or negative one)
