A male aged 3 -5. They only need 500mg of calcium!
Scandium is in the group 3, calcium in the group 2 of the periodic table.
Calcium -period 4 group 2a- chlorine group 7A -halogens-
ester
potassium is in group 1 and calcium in group 2, so potassium has 1 valence electron and calcium 2.
According to the periodic table that would be calcium
It may contain a trace amount but carbohydrates, as a food group, are not a source of dietary calcium.
Calcium is in group 2 of the Periodic Table. The group consists of beryllium, magnesium, calcium strontium, barium and radium. Calcium is in period 4.
Calcium is in group 2 of the periodic table. The group consists of beryllium, magnesium, calcium strontium, barium and radium. Calcium is in period 4.
The element calcium is a metal. It turns out that calcium (Ca) is in Group 2 of the periodic table, and all the elements in Group 1 and Group 2 are "true" metals.
No, calcium is not in the halogen group. The halogen group is made up of fluorine, chlorine, bromine, iodine, and astatine.
No. Barium and magnesium and calcium are in group 2A but potassium is in group 1A.
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
Scandium is in the group 3, calcium in the group 2 of the periodic table.

Calcium -period 4 group 2a- chlorine group 7A -halogens-
Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
second group
