If, by "equal groups", you mean groups of equal things, you get how many in all [the total number] by simply addingthem all together. Sometimes adding is called summation.If, by "equal groups", you mean equal-sized groups of things, you get how many in all by multiplying the number of groups by the number of things in each member group.The number of things in a group is also called its cardinality. Loosely, cardinality is the size of the group, or the number of elements ["things"] in the group.
The definition of equal groups are having the same number of units in each group. An example is how would someone put 15 items in 3 equal groups. Each group would have 5 items.
When you have finished dividing, the divisor (the number you divided BY) and thequotient (the answer you got) together, are both of those numbers, either way.Either of them can be the number of equal groups, and then the other one is thenumber in each group.
Combining equal groups together is possible through the concept of multiplication. By multiplying the number of groups with the number of items in each group, you can determine the total number of items. For instance, if you have 3 groups with 4 items in each group, you can put them together by multiplying 3 x 4 to get a total of 12 items.

It is the number in each group multiplied by the number of groups.

There are three possibilities:-- 7 equal groups, with 3 in each group-- 3 equal groups, with 7 in each group-- 21 equal groups, with 1 in each group

The column number on the periodic table corresponds to the number of valence electrons an element has. Elements in the same column have the same number of valence electrons, which influences their chemical properties and reactivity.
For main group elements (groups 1, 2, 13-18), the number of valence electrons is equal to the group number. For transition metals (groups 3-12), the number of valence electrons can vary. An atom's valence electrons control its chemical properties and reactivity.
The periodic table of Mendeleev has 18 groups.
All elements in Group 7 have the same number of electrons in their outermost shell and this number corresponds to the group number.
G = C/6 where C is the number in the class and G is the number in each group.
