Chemical compound
The numerical average of a group of numbers is the ratio of the sum of group of numbers to the total amount of numbers. This is also known as the mean.
Average of the numbers in a group =(the sum of all the numbers in the group) divided by (the number of numbers in the group)
There are three groups of numbers on the bottom of checks. The first group is nine numbers; it is your bank's routing number. The next set of numbers is either your checking account number or your check number. The longer group is your account number and the shorter set of numbers is your check number. Why they are strange looking depends on what is meant by strange looking. There are some symbols which make them look a bit strange. Those are probably used by the bank in some way or may be a way to separate the groups of numbers.
You group the numbers 11,12,1,2.Then you group the numbers 10,9,3,4.last you group the numbers 8,7,6,5.
The middle number out of a group of numbers.
Chemical formula
A Chemical formula
This combination of symbols is known as a chemical formula.
The groups of symbols are called "formulas" (Latin formulae) because they show the symbols of the elements and ions that are in a molecule of a compound.Example: CO2 (carbon dioxide) contains one atom of carbon and two of oxygen.
It stands for an amino group.
An element and compound. Element- A group of atoms with identical proton numbers, Compound- 2 or more DIFFERENT elements chemically held together.
As the need for larger numbers increased, it became necessary to use symbols to group numbers together to form larger numbers. Some examples of number representation are roman numerals as well as unary, binary and decimal code.
Have a look at the periodic table page on wikipedia. I cannot make out the numbers of the groups.
Name 2 chemical symbols that belong to group 8 group 1period 6 and period 5?
For any group, state or nation, symbols are what we mortals rally around.
The average of a group of numbers is(the sum of all the numbers in the group)/(how many numbers there are in the group)
By adding up all the numbers in the group and dividing by the number of numbers in the group.
