  1. A solution that has a higher concentration of hydrogen ions than hydroxide ions.
    Acid
  2. The smallest indivisible building block of matter. Each atom is made up of a nucleus and an electron shell.
    Atom
  3. The "weight" if an element determined by the addition of the protons and the neutrons. The result is expressed in "atomic mass units."
    Atomic mass
  4. a number assigned to every element that corresponds to the number of protons in the nucleus of the most common form of the element.
    Atomic Number
  5. a one or two letter abbreviation to identify an element.
    atomic symbol
  6. a solution that has a higher concentration of hydroxide ions than hydrogen ions.
    base
  7. a commonly used model to describe how atoms look and interact with one another
    bohr model
  8. electrons combining together from different atoms resulting in the formation of a molecule
    chemical bond
  9. equal sharing of electrons between atoms involved in a chemical bond.
    covalent bond
  10. the "falling apart" (or dissolving) of ions in a solution
    dissociate
  11. negatively charged subatomic that orbit the nucleus of an atom.
    electron
  12. the area outside of the nucleus where the electrons are found orbiting the nucleus.
    electron shell
  13. a group of the same atom bonded together an element is matter composed only of the same type of atom.
    element
  14. bonds that form between hydrogen and polar molecule in a solution containing polar chemical bonds.
    hydrogen bonds
  15. an atom that has a positive or negative charge.
    ion
  16. a chemical bond that forms due to the attraction  of a positive ion to a negative ion.
    ionic bond
  17. different forms of the same element that differ only in the number of neutrons.
    isotope
  18. the law that no mass can be lost of destroyed in a chemical reaction; the number of atoms on the reactant side must equal the number of atoms on the product side.
    law of conservation of mass
  19. the quantity of matter an object has.
    mass
  20. anything that takes up space and has mass matter can exist in solid liquid or gas forms.
    matter
  21. a group of two or more atoms bonded together
    molecule
  22. a neutrally charged subatomic particle located in the nucleus of an atom.
    neutron
  23. a covalent bond resulting in the electrons being equally shared by the atoms of the bond.
    no-polar bond
  24. the center part of the atom that contains protons and neutrons.
    nucleus
  25. the property of chemical that results in eight electrons filling the outer shell.
    octet rule
  26. the measurement of acidity or basicity of a solution
    ph
  27. a covalent bond resulting in electrons being slightly more attracted to one atom of the bond than the other
    polar bond
  28. the resulting molecules from a chemical reaction.
    product
  29. a positively charged subatomic particle that is located in the nucleus of an atom it has a mass of one atomic unit.
    proton
  30. elements or atoms that take place in a chemical reaction or bond.
    reactants
  31. the molecules of a solution that are in lower quantities.
    solute
  32. a homogeneous combination of atoms in a liquid solid or gas.
    solution
  33. the molecules of a solution that are in greater quantities.
    solvent
  34. particles that are smaller than an atom although there are more than three, the ones we learned about are the proton, neutron, and electron.
    subatomic particles
  35. What is the process of making sugar for plants called?
    Photosynthesis
  36. how many processes do plants have to make atp?
    2
  37. what is the process of making molecules of atp from sugar called?
    Cellular respiration
  38. what are the four most common types of atoms?
    hydrogen nitrogen oxygen and carbon
  39. what is the universal fuel to all organisms for metabolism?
    Sugar
  40. what is the difference between an acid an a base?
    an acid is an object with a low ph, while a base is an object with a high ph.
  41. what are anabolic reactions?
    they are reactions which synthesize organic molecules, meaning it is bringing molecules together to make a polymer
  42. what is a polymer
    it is more than one molecule joined together to make a larger substance
  43. what are catabolic reactions
    it is the process of taking molecules formed together and breaking them apart
  44. what is a monomer?
    it is like a polymer but opposite, a monomer is the molecules broken apart by catabolic reactions just to form one molecule instead of more than one like a polymer
  45. what is dehydration synthesis?
    it is the process of removing all of the water from a cell and evaporates it
  46. what forms the borders of the cyclic model for glucose and fructose?
    carbon
  47. to find the actual formula of amylose for any type of molecule of chemical equation what do you dp?
    you multiply the equation by 60
