Making your own Dichotomous Key Assignment Your task is to pick 15 animals or creatures or characters or objects and
identify them using a dichotomous key. Examples of things you can choose
are characters from a cartoon show, types of fishes, types of cars,
individuals in biology class. Here are a few simple rules that you must follow:
• Make two dichotomous keys: a) visual dichotomous key
b) written dichotomous key
• Include at least 15 organisms (object) in your key. A picture
and a SCIENTIFIC name must be provided for each
organism (object). You can create the scientific name if
there isn't a real one.
Each statement must have a yes and no answer

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
