What is a chemical bond?
01. CHEMICAL BOND
CHEMICAL BOND
--- is a force that holds of two or more atoms together
and makes them function as a unit.
-- is the physical phenomenon of chemical substances
being held together by the attraction of atoms to each
other through sharing, as well as exchanging of
electrons or electrostatic force.
What causes this forces?
-- bonds are formed when constituent atoms come close enough
together such that the outer electrons of one atom are attracted to the
positive nuclear charge of its neighbor.
02. TYPES OF CHEMICAL BOND
What are the different types of
chemical bond and how are each
type formed?
The type of bonding is determined by how
the outermost electrons of an atom, the
so-called valence electrons interact with
neighboring atoms.
The position of an element in the
periodic table determines the
type of bonds it makes.
IONIC BOND
-- results from the transfer of electrons from one element to another
Types of Chemical Bond
COVALENT BOND
-- results from the sharing of electrons between two atoms
IONIC BOND
-- form between a metal and nonmetal.
Types of Chemical Bond
COVALENT BOND
-- formed when two nonmetals combine; also formed when a
metalloid bond to a nonmetal.
IONIC BOND
When sodium and chlorine react to form sodium chloride, electrons are
transferred from the sodium atoms to the chlorine atoms to form Na- and
Cl- ions,, which the aggregate to form solid sodium chloride.
Calcium Chloride
CaCl2
Ca would have a charge of 2+ since it
lost two electrons.
Each Cl ion would have a charge of 1-
since each gained an electron. A
subscript “2” is used to show that two
ions were used in the bond
Magnesium Chloride
MgCl2
Mg would have a charge of 2+ since it
lost two electrons.
Each Cl ion would have a charge of 1-
since each gained an electron. A
subscript “2” is used to show that two
ions were used in the bond
