Matter Study Guide

3. Each of more than 100 elements of matter has distinct properties and a distinct atomic structure. All forms of matter are composed of one or more of the elements.

3.a. The structure of an atom is composed of protons, neutrons, and electrons.
Subatomic Particle / Proton / Neutron / Electron
Location
Charge

Draw the protons, neutrons, and electrons of a Bohr model of the Nitrogen atom. Label the nucleus.
# of Protons ______
# of Neutrons ______
# of Electrons ______
How do electrons move? ______
3.b. Compounds are formed by combining two or more different elements and compounds have properties that are different from their constituent elements.
(p.186) Na + Cl → NaCl
(sodium) (chlorine) (salt) / (p. 64) Ca + CO2 → CaCO3
(calcium) (carbon dioxide) (calcium carbonate)

3.c. Atoms and molecules form solids by building up repeating patterns, such as the crystal structure of NaCl or long-chain polymers

3.d. The states of matter (solid, liquid, gas) depend on molecular motion.
3.e. Students know that in solids the atoms are closely locked in position and can only vibrate; in liquids the atoms and molecules are more loosely connected and can collide with and move past one another; and in gases the atoms and molecules are free to move independently, colliding frequently
