- What are non-polar covalent bonds?
- What is a chemical reaction? Be able to identify the products and reactants in a chemical reaction.
- What is electronegativity?
- Define Subatomic particles, their charges, where they're found, and their relative mass.
- What are valence electrons?
- a The electrons on the outermost orbital shell
- b One atom's attraction of the electrons within one covalently bonded molecule
O > N > C > H
Oxygen - most electronegative element
- c The making and breaking of chemical bonds.
1. Reactants - structure of chemicals prior to a chemical reaction
3. Products - structure of chemicals as a result of a chemical reaction
- d The sharing of electrons EQUALLY; atoms have similar electronegativities
- e Protons - positive; in nucleus; 1 dalton (or amu)
Neutrons - neutral; in nucleus; 1 dalton (or amu)
Electrons - negative; found outside nucleus; 0 nothing
5 Multiple choice questions
- Anything that takes up space and has mass. Ex: Air; something that isn't matter: light (think of the filling up a balloon metaphor)
- Atoms that lose or gain electrons to complete their outer shell
- Ex: O - only 6 rings on outer shell, so it wants to gain 2, making it 2- charge
- Polar covalent bond.
(it's when there's more than one polar molecule that hydrogen bonding takes place)
- Atoms interacting with each other to share, take, or give electrons.
5 True/False questions
What are our 6 Essential Elements? → CHNOPS: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur
What are the two strong chemical bonds? → Atoms interacting with each other to share, take, or give electrons.
What are isotopes? → Different forms of the same element; they differ in number of neutrons, but they have the same # of protons and behave identically in chemical reactions
What are covalent bonds? Single? Double? → The electrons on the outermost orbital shell
What are ionic bonds? → Electron gaining or losing; e⁻ TRANSFER (NOT SHARING) between two atoms
