Answer:
1st column group 1 - group2
second column Halogen group - zero group ( inert gases )
third column - very active metals , tend to lose one electron -less reactive than group one , tend to lose 2 electrons - very active nonmetals, tend to gain one electron - Nobel gases , do not gain or lose electrons
Explanation:
Answer:
I think it might be elements and compounds! I may be wrong though.
The answer is true. i’m sorry if i get this wrong.
A solution with a Ph of 2 has a H+ ion concentration that is two times greater than a solution with a ph of 4. The Ph of 2 and 4 indicate that the solution is acidic since they are less than PH of 7. The H+ ions are more present when the solution is acidic but the Ph differ with concentration H+ ions. The solution with a Ph of 2 has more H+ than the solution with Ph of 4 thus the solution with Ph of 2 has more hydrogen ions than that of 4
