Covalent Bonds Nature
The ability of an atom to draw electrons toward itself to create a bond and its tendency to lose, gain or share electrons when it combines.
What is Electronegativity?
Smallest particle of an element
atom
What are some Physical Properties of covalent bonds?
Relatively low melting and boiling points Gases at room temperature Poor electrical and heat conductors Many of them are soluble in non-polar liquids Molecules
Gilbert Newton Lewis
Who discovered Covalent bonding?
How many valence electrons does each element have to be stable in a covalent bond?
eight?
When the electronegative force of both elements is somehow equal.
When is a a covalent bond formed instead not an ionic bond?
Polar Covalent Bonds Non-polar Covalent Bonds
What are the names of the two species of covalent bonds?
No ions are formed
Why they don't conduct electricity
U.S.A
Where was Gilbert Newton Lewis from?
Bonds that share electrons are called
covalent bonds
A big difference in the electronegativity of the atoms.
What characteristic makes an ionic bond instead of a covalent bond?
Polar Covalent Bonds
unequal sharing of electrons
How do atoms in covalent bonds act?
They act in a stabilized manner.
Copernicus
Father of astronomy
particles found in the nucleus
protons and neutrons
A chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion
What does Ionic bond mean?
Non-polar Covalent Bonds
equal sharing of electrons
Why do bonds break easily in covalent bonds
low melting point does not require a lot of energy to break
In 1704, Isaac Newton
Who and when formulated the atomic bond theory?
why do water and oil not mix
one is polar and one is nonpolar
When two pairs of electrons are shared what is formed
double bond
Diagram used to model covalent bonds

Fluorine
non polar
Galileo
Father of the Scientific Method
