Fact, Theory, The Scientific Method
The first step of the Scientific Enterprise
Observation!
NaCl is also known as...
Table salt
Give the chemical formula for water
H2O
Type of chemical bond where one atoms steals an electron and the other atom gives away an electron
Ionic Bond
A Carbohydrate is another name for what common type of food/fuel?
Sugar
Define a Theory
A collection of provable results from repeated experiments, that form the basis of understanding on a topic
The most electronegative of all elements
Fluorine
The atomic number (the number above each element) represents this positively charged subparticle in the atom
Proton
The strongest, most prevalent chemical bond in all of life. A true representative of our Covenant God.
Covalent Bond
What element/atom is the foundation of ALL organic molecules?
Carbon!
The way things really are
The element that has only 1 valence electron and 1 proton in the nucleus
Hydrogen
What rule do most elements/atoms follow when it comes to reaching stability in their valence electron shell (number of electrons to make them happy)
Octet rule
When two atoms share electrons, but one has a stronger electronegativity than the other, forming a slight charge on either end of the molecule
Amino acids are the building block of this organic molecule
Protein
Hypothesis
The name given to the perfectly stable gases on the far right of the periodic table
The number of valence electrons that the element Carbon has, causing it to be overall neutral.
4 electrons
What kind of bond is represented by the magnetic attraction between water (H2O) molecules that causes much of water's unique properties.
Hydrogen Bonding
The type of organic molecule that makes up our DNA
Nucleic acids
If your experiment does not prove your hypothesis correct, what step does a scientist take next?
Analysis/Review, and restart the experiment
The name given to elements that have differing numbers of NEUTRONS in the nucleus
Isotopes
The name of the first model given to diagram the atom (nucleus and the outer electrons in their orbits)
The Bohr Model
The form of bond that Carbon forms with Hydrogen to form Methane (gas), resulting in a neutral overall charge
Nonpolar Covalent Bond
The organic molecule is what forms hydrophobic barriers, such as the cell membrane
