Mar 27, 2022 · Multiplying 5 and \(\frac{2}{5}\) allows us to check this answer: \(5\cdot\frac{2}{5}=\frac{10}{5}\) and \(\frac{10}{5}=2\), so the answer is correct. Notice the number of groups that result from \(2\div\frac{2}{5}\) is a whole number.
Sorted by: 37. Finding generators of a cyclic group depends upon the order of the group. If the order of a group is 8 then the total number of generators of group G is equal to positive integers less than 8 and co-prime to 8 . The numbers 1, 3, 5, 7 are less than 8 and co-prime to 8, therefore if a is the generator of G, then a3, a5, a7 are
Jun 23, 2021 · The number of valence electrons depends on the octet rule. For example, elements in group 1 have 1 valence electron, elements in groups 3-12 have a variable number of valence electrons, and elements in group 17 have 7 valence electrons. The lanthanides and actinides, located below the main table, all fit within group 3. There are 18 element groups.
