Cornell Notes
Reduce & then Recite
- Create questions which elicit critical
thinking, not 1 word answers
- Write questions directly across from
the answers in your notes
- Leave a space or draw a pencil line
separating questions
What is the atomic number
In this picture?
what type of diagram is
This?
Record for Review
- Write headings and key words in colored pencil
- Take sufficient notes with selective (not too many words) & accurate
paraphrasing
- Skip a line between ideas and topics
- Use bulleted lists and abbreviations
- Correctly sequence information
- Include diagrams or tables if needed for clarification or length
The atomic number of proton and electrons in the nucleus of an atom, which
determines the
Chemical properties of an element and its place in the periodic table.
Bohr: a theory of the structure of atoms stating that electrons revolve in
Discrete Orbits around a positively charged nucleus and that radiation is given
Off or Absorbed only when an electron moves from one orbit to another.
what is a compound?
A compound is a pure substance that is composed of two or more atoms
combined
what is a covalent bonding?
A covalent compound is made when two or more nonmetal atoms bond by
sharing valence electrons.
What is an ionic bonding?
Ionic bonds form when one atom gives up one or more electrons to another
atom.
What is an ion?
an atom or molecule with a net electric charge due to the loss or gain of one or
more electrons
What type of diagram is
this?
Lewis: Some uses are finding the valence electrons, show of ionic compound,
showing of covalent molecules, and showing of diatomic molecules.
what is a valence electron?
the electrons that are in the valence shell of an atom.
What four sections is the
periodic table organized?
The four sections that the periodic table is organized are Metal, non-metal,
halogens, and noble gases.
Define a subatomic particle?
The particles that make up the atom.
What are examples of metals
that are multivalent?
The ability of an element to form ions in more than one Way (iron, cooper, lead,
mercury, magnesium, nickel)
What is the outermost shell
The outermost shell is called the valence shell Which holds all the valence
Electrons.
Valence electrons
both atoms in the bond contribute one valence electron in order.
to form a shared pair.
What is a Chemical change?
a process that involves rearrangement of the molecular or ionic structure of a
substance, as opposed to a change in physical form or a nuclear reaction.
Reflect & Recapitulate
In your own words and in complete sentences, write a 3 – 4 sentence summary paragraph. Your summary should cover the main
concepts of the notes, be accurate, and have adequate details.
Lesson 4.1 was about chemical bonding and atomic theory and the information above’s focus is
using the periodic Table and bonding it to chemicals and showing how many protons, electrons,
neutrons, and showing that you know the difference between Bohr and Lewis diagrams and know
how to draw them. This was important to this Unit because the diagrams showed what the atoms
do to bond together and what happens to the extra electrons And, used them to stabilizing ionic
ionic compounds, covalent compounds, diatomic molecules and finding valence Electrons before
before it happens. One big part of this chapter was understanding all about the periodic table with
Electrons before it happens. One big part of this chapter was understanding all about the periodic
table with all the Elements symbols, the atomic mass and numbers to the elements and the ion
charge of the element. You really need to know the periodic table. In conclusion, the information that
that was important was both the diagrams the Lewis and Bohr diagrams, and the basics of the
of the periodic table.
