Ionic compounds are formed by the bonding of non-metals to metals. Because inonic bonds involve electon transfer, the result is a mixture of ions; positive and negative, following the laws of electrostatics, like charges attract. These ions then form a giant structure (lattice) of ionic bonds and it is because of this that ionic compounds are solids (unless dissolved in water) and have extremely high melting and boling temparatures. In additions, beucase of the fixed placement of ions (charged particles) in a lattice, in the solid state ionic compounds don't conduct electricity very well but if dissolved in water (aqueous solution) the ions are free to move and carry a current.
The (2) calcium atom, because when looking at the periodic table, we see that the calcium atom is in a location where according to the periodic table, has the lower electronegativities in respect to the other three choices. We see that it also has a lower electronegativity value than the others. Electronegativity is the attraction constant for the electrons in a chemical bond. The higher the electronegativity, the higher the attraction of the electrons. Fluorine has the highest electronegativity with 4.0.

Explanation:
A. Initial observation
Gary's shell had slime and an odour.
B. Independent variable
The independent variable is the one that the experimenter changes.
There are two independent variables: the rubbing with seaweed and the drinking of Dr. Kelp.
C. The dependent variable
The dependent variable is the amount of slime and odour.
D. The conclusion
Sponge Bob can conclude that rubbing the shell with seaweed and drinking Dr. Kelp removes the slime and odour.
However, this was a poorly designed experiment. He doesn't know if it is the seaweed or the Dr. Kelp that gives the result or if he must use both together. He should change only one independent variable at a time.
