1. Data Signal Group 2. Address Signal Group 3. Common Clock Signals
I'm sorry, you will need to be more specific. Your question is in 3 different categories, I'm not sure which is the most relevant. Which type of group are you referring to ?
3 items each in 3 categories gives 3*3*3 = 27 possible combinations.
Alkali earth metals (group 1) halogens (group 6) and transition metals/metaloids (middle group) there is also poor metals lanthanoids actanoids and a few others
GHS has more than 3 categories. Basically we can consider groups as Labels and Safety Data Sheets (SDS). Each group contains many classes. Within the GHS classification system, there are three major hazard groups:Physical hazards.Health hazards.Environmental hazards
