According to the tag info, a binomial heap is a forest of binomial trees. And according to this wikipedia article, the number of elements in each tree must always be a power of 2. Furthermore, there can only be one tree of each size. So, for example, if there are two trees of size 4, then they need to be combined into a single tree of size 8.
So a binomial heap with 10 elements consists of two trees: a tree with 8 elements, and a tree with 2 elements. Which means your heap is as shown below. The 1 and 2 aren't connected to the other eight elements. They are in a separate tree.
The dotted lines can be ignored. The image source is the wikipedia article, and I just filled in the numbers.
