Lab 1 Flashcards
is the joining of two atoms in a stable arrangement
Bonding
Elements will ____, _____, or ____ electrons to reach the electron configuration of the noble gas closest to them in the periodic table.
gain, lose, or share
two different kinds of bonding
- Ionic Bonding
- Covalent Bonding
result from the transfer of electrons from one
element to another
Ionic bonds
result from the sharing of electrons between two atoms
Covalent bonds
are formed when two nonmetals combine, or when a metalloid bonds to a nonmetal
Covalent bonds
is a compound or element containing two or more atoms joined together with covalent bonds
molecule
a ____ on the left side of the periodic table
metal
a ______ on the right side of the periodic table
nonmetal
gives electrons
Metals
receives electrons
Nonmetals
are charged species in which the number of protons and electrons in an atom is unequal
Ions
consist of oppositely charged ions that have a strong electrostatic attraction for each other
Ionic compounds
There are two types of ions
cations and anions
are positively charged ions
Cations
A cation has _____ electrons (e−) than protons
fewer
are negatively charged ions
Anions
An anion has _____ e−than protons
more
a main group element is especially stable when it possesses an octet of e−in its outer shell
octet rule
how many valence electrons for the octet rule?
8
groups 1A - 3A charge
group number
groups 6A - 7A charge
8 - group number
The sum of the charges in an ionic compound must be
zero overall
is a cation or anion that contains more than one atom
polyatomic ion
lesser charge
“ous”
greater charge
“ic”
