How are families of the periodic table named?
The Periodic table can be divided into nine families of elements each having similar properties. The families include: Alkali metals Alkaline metals The Transition metals Other metals Metalloids Non-metals Noble gases Rare Earth
When writing a number in scientific notation how many numbers should be on the left side of the decimal point?
Usually only one digit is to the left of the decimal point in scientific notation. For example, 240 is written as 2.4x10^2 while .00035 would be written as 3.5 x 10^-4. In some instances, however rare they are, you may see expressions such as 24x10^1 or 35x10^-3, and so on.
