Calcium is in group 2/IIA, so the other elements in that group would be expected to behave most like calcium.
Strontium is similar to calcium.
I would expect it is Silicon, same as on Earth.
Our GI tracts cannot absorb calcium unless it is ionized in a compound, such as calcium carbonate. A great source of calcium carbonate is crushed oyster shells.
you only find 1 type of atom in an element
I would imagine, logically, Calcium would react with every element except the Noble Gases - as they already have full outer energy levels, thus being unreactive. You will often find one calcium reacting with one element from group 6, for example Oxygen. CaO (as they strive to reach a full outer shell.)
This value is identical for isotopes.
Ge Germanium
Ge Germanium
yes because it id a natural element and you would get it and make milk out of it
Silicon (Si) behaves most like Carbon (C).
One is magnesium. Other is Strontium. One below and one above Calcium in periodic table column.
Calcium
It would be a compound, made of Calcium and Oxygen.
Helium
what do you expeat to find in calcium chloride in ocean water
calcium
Like all metals calcium will lose electrons.
A compound, and it's name would be calcium oxide.
