What is the comes first kilogram hecagram decagram then gram etc?
In SI measurements, a whole has no prefix. Getting smaller progressively from the whole, the prefixes go: deci-, centi-, milli-, micro-, nano-, pico-. Getting progressively bigger from the whole, the prefixes go: deca-, hecto-, kilo-, mega-, giga-, tera-. So gram comes first as it is the unit. The others are just multiples of this unit to make the numbers easier.
What is the difference between metric system and natural system?
Both came from something that was observed naturally, and came from the need to facilitate trade. The metric system, however, based it's measurements on standards that could be replicated, and there was the base unit with multiplier prefixes. So while the natural system (or customary system) has for length measurements (inch, foot, yard, mile, etc) the metric system only has the meter and then multiples of meter (like centimeter is 1/100 of a meter, or kilometer is 1000 meters).
How do the prefixes in the metric system?
In the metric systems, unlike other systems, there is only one unit for each measurement; e.g the only unit for length is the metre. For lengths much longer, or shorter, lengths we use prefixes to indicate the fraction or multiple of the metre. For short lengths the fractions are thousandths, millionths, billionths; for which the prefixes are milli-, micro-, and nano-. For longer lengths, the multiples are thousands, millions, and billions; for which the prefixes are kilo-, mega-, and giga-. The prefixes indicate the fraction,or the multiple of the base unit.

What pairs of prefixes are closest to each other in size?
Which of the following pairs of prefixes are closest to each other in size?
List SI units of measurements and common SI prefixes?
SI units of measurements: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount of substance), candela (luminous intensity). Common SI prefixes: kilo- (k, 10^3), mega- (M, 10^6), giga- (G, 10^9), milli- (m, 10^-3), micro- (μ, 10^-6), nano- (n, 10^-9), pico- (p, 10^-12).

Why do scientists prefer using the metric system rather than the English system to make measurements?
1) It is an international standard, so all scientists use the same measurements. For comparison, for example, different countries have different definitions of a pound. 2) Calculations are easier, because of the decimal prefixes.
What is the appropriate chemical name for Na2S?
It is an ionic compound, so its name is sodium sulfide. Greek prefixes are not used when naming an ionic compound.
