There are 7.
7 groups of 4000= 7 x 4000 7 x 4000 = 28 000
7 groups, with 3 in each3 groups, with 7 in each21 groups, with 1 in each1 group, with 21 in each
To find out how many groups of 7 equals 21, you can divide 21 by 7. The result is 3, which means there are 3 groups of 7 in 21. This is because when you multiply 7 by 3, you get 21. So, there are 3 groups of 7 that equal 21.
Modern periodic table has 7 periods and 18 groups.
Yes, 21 can be divided into equal groups. 21 is divisible by 1, 3, 7, and 21. Therefore, you can divide 21 into 1 group of 21, 3 groups of 7, 7 groups of 3, or 21 groups of 1, with each group being equal in size.
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

Yes. It can be divided into -- 21 equal groups of 1 each -- 3 equal groups of 7 each -- 7 equal groups of 3 each
The columns are called groups and rows are called periods. There are 18 groups and 7 periods.
