Does percent error measure accuracy or precision?

Precision

Explanation:

It figures out how close all of the data numbers are.

I believe it is accuracy

Explanation:

When preforming experiments accuracy and precision refer to two separate things.  Accuracy is how close to the actual value you are while precision is how grouped your values are.  The goal is to have both high accuracy and high precision. Standard Deviation is a measurement used for precision while Percent Error is a measurement used for accuracy.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
