based on valence electrons pattern using the
periodic table model

design simple reactions that result in two main classes of
binary compounds, ionic and molecular. Develop an
explanation based on given observational data and the
electronegativity model about the relative strengths of ionic
or covalent bonds.

Share your thoughts and describe how do
Na and Cl atoms turn into ions.
●
Na atom lost 1 electron to be stable according
to octet rule and becomes Na+
●
While Cl atom gains 1 electron to be stable
according to octet rule and becomes Cl-

Ion Formation
Valence Electrons and Chemical
Bonds
Electron-dot structures can be used to
illustrate the formation of chemical bonds.
Valence Electrons and Chemical
Bonds
• Ionization energy refers to how easily an
atom loses an electron.
• Electron affinity indicates how much
attraction an atom has for electrons.
• Noble gases, which have high ionization
energies and low electron affinities, show
a general lack of chemical reactivity.
• Noble gases have electron configurations
with a full outermost energy level.
Valence Electrons and Chemical
Bonds
• Elements tend to react to acquire the
stable electron structure of a noble gas.
• Atoms try to form an octet—a stable
arrangement of eight valence electrons in
the outer energy level—by gaining or
losing valence electrons.
Positive Ion Formation
• A positive ion forms when an atom loses
one or more valence electrons in order to
attain a noble gas configuration.
• A positively charged ion is called a cation.
Positive Ion Formation
• This figure illustrates how
sodium loses a valence
electron to become a
sodium cation.
• By losing an electron, the
sodium atom acquires
the stable outer electron
configuration of neon.
Positive Ion Formation
• Transition metals commonly form 2+ or 3+
ions, but can also form ions of 3+ or greater.
• Other relatively stable electron
arrangements are called pseudo-noble gas
configurations.
Negative Ion Formation
• Non-metals easily gain
electrons to attain a
stable outer electron
configuration.
• The figure shows chlorine
gaining an electron.
• An anion is a negatively
charged ion. Thus, the
chlorine atom becomes a
chloride anion.

Analyze the following image
and then answer the question
Let’s spread positivity. How would these
elements behave to become positive?
These elements are metals so they
will lose electrons to become stable
so they will be positive

Explain how the transition metals
lose electrons. Justify your answer.
Transition metals lose electrons from
the valence shell first, which is not the
last subshell. This means that they are
going to lose electrons from the last s.
