Answer:
Nickel (Ni) is most likely to form more than one kind of positively charged ion as it is a transition metal and all of the ther metals have a fixed ion charge.
Na becomes Na+
Ba becomes Ba +2
Mg becomes Mg+2
Explanation:
please mark brailiest
metal atoms lose electrons to form positivity charged ions. non metal atoms gain electrons to form negatively charged ions
0.1 M HCl pH: 1-2
0.001 M HCl pH: 3-4
0.00001 M HCl pH: 5-6
Distilled Water pH: 7
0.00001 M NaOH pH: 8-9
0.001 M NaOH pH: 10-11
0.1 M NaOH pH: 12-13
Volume:-
So
Ca: 1
Cl: 2
Since there is no subscript but there is the element, its assumed that there is at least 1, otherwise it would'nt be there
