Chemical Bonds
2.
Biological, chemical, and physical properties of matter result from the ability of atoms to form bonds
from electrostatic forces between electrons and protons and between atoms and molecules. As a
basis for understanding this concept:
a.
Students know atoms combine to form molecules by sharing electrons to form covalent or
metallic bonds or by exchanging electrons to form ionic bonds.
b.
Students know chemical bonds between atoms in molecules such as H2 , CH4 , NH3 , H2
CCH2 , N2 , Cl2 , and many large biological molecules are covalent.
c.
Students know salt crystals, such as NaCl, are repeating patterns of positive and negative
ions held together by electrostatic attraction.
d.
Students know the atoms and molecules in liquids move in a random pattern relative to
one another because the intermolecular forces are too weak to hold the atoms or
molecules in a solid form.
e.
Students know how to draw Lewis dot structures.
