Atomic Structure: (sol 6.4 a)
1) Matter – anything that has mass and takes up space (volume).
2) 4 States of Matter; Solid, Liquid, Gas, Plasma
3) The structure of the atom and it’s properties:
protons- a positively charged subatomic particle, found only in the nucleus. The atomic number
states the number of protons.
neutrons- a subatomic particle with no electric charge that is found in the nucleus. An atom with an
abnormal amount of neutrons is considered an isotopes. Neutrons have the same mass as a
proton.
electrons- a negatively charged particle moving around the nucleus of the atom. Its mass is
thousands of times smaller than either a proton or neutron so it does not affect the atomic
mass number.
4) Atomic Structure can be represented

Essential Elements and compounds (6.4-g)
1.)A limited number of elements, including, silicon, aluminum, iron, sodium, calcium,
potassium, magnesium, hydrogen, oxygen, nitrogen, and carbon form the largest portion of the
Earth’s crust, living matter, the oceans, and the atmosphere.

Elements: (sol 6.4 a,b)
1) An element is a form of matter made up of only one type of atom. (Copper is only of copper atoms.)
- Comparison of 2 different elements atomic structure in the Bohr model.
2) Atoms of any element are alike but are different from atoms of other elements;
ex. - Copper atoms are different from other types of atoms because of the number of protons in
their nucleus)
3) Atoms are generally electrically neutral (P = N).
4) Elements can vary in the number of neutrons (isotopes) or electrons (ions)
they have but cannot change the number of protons that they have.
-isotopes – are the same element but have different
numbers of neutrons.
Example: Carbon 12 & 14

Lab: Elements –ws#5
1) Elements may be represented by chemical symbols (Uppercase/lower case);
2) All elements can be found on the Periodic Table, there are 92 that occur naturally in the universe.
-All others are synthetic and developed in particle accelerators.

Periodic Table Properties (sol 6.4 c)-There is a periodic table in your agenda!!
a) -The Atomic Mass is determined by the number of protons and neutrons (in the nucleus).
b) -Elements are arranged according to increasing atomic number.
c) what it means to be organic – the compound contains carbon
- The atomic numbers increase as you move across the periodic table.
- Symbols on the Periodic chart are based on the Latin work for that particular element.
- Honors: PT rows tell the number of shells, PT columns tell the number of electrons on the
outer shell.
d) The periodic table is also categorized into metals, nonmetals, and semimetals.
Please understand that the science class is fluid and items listed here may change. This is a guide for this unit we will be doing more activities.
