Explanation:

1. Precision is how close experimental values are to one another or also defined as the reproducibility of a result i.e. the ability to reproduce a measurement.

2. Instrument precision, also called Injection precision, is the reproducibility of an instrument reading when the same amount of one sample of what is being measures is introduced repeatedly into an instrument.

3. Intra-assay precision is the reproducibility of measurements on the same material several times by one person on one day with the same equipment.

4. Intermediate precision is also called Ruggedness and it refers to the reproducibility of measurements by different people, on different days, on different pieces of equipment within the same laboratory.

5. Interlaboratory precision is the reproducibility of a measurement from the same sample by different people in different laboratories

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
