Module 3 Flashcards
1
Q
They are formed when atoms lose, accept or share electrons.
A
Chemical bonds
2
Q
- Occurs when there is a transfer of one or more valence electrons form one atom to another.
A
Ionic bond
3
Q
When two nonmetal atoms combine, neither of them loses or gains electron.
A
Covalent bond
4
Q
- Substances have different polarities, and this explains why there are substances that do not mix while others do.
A
Polarities
5
Q
The polarity of molecules is determined by the two factors
A
o The polarity of bonds based on the electronegativity difference of the atoms involved
o The geometrical shape of the molecules which can be predicted via valence shell electron pair repulsion (VSEPR) theory.
6
Q
- Measures the relative tendency of an atom to attract electrons to itself when chemically combined with other atom.
A
Electronegativity (EN)
7
Q
which will help us in predicting what type of chemical bond (ionic, polar covalent or nonpolar covalent) that would exist between them.
A
absolute electronegativity difference (AEN)
