What element is the 3rd element?
lithium is the third element. It is placed in group-1
How many element combos are there?
The total number of element combinations depends on the number of elements that are being combined. For example, if you are combining 2 elements, there would be a total of 2 combinations (element 1 + element 2). If you are combining 3 elements, there would be a total of 6 combinations (element 1 + element 2, element 1 + element 3, element 2 + element 3). The formula to calculate the number of combinations is n(n-1)/2, where n is the number of elements being combined.
