All elements can and many often do form positive ions.
magnesium
Cation is a positive ion, not an element; for metals the symbol is Mex+.
Negative ion. Cl-
Because group 1 has 1 electron in it's outer most shell and the have to fill the energy level, so they gave there electron and form positive ion (cation). And group 17 has 7 electrons in it's outer most shell and they need to complete their shell so the gain electron and form negative ion (anion).
Negative (Fl-) All the halogens become negative ions.
No it forms Mg2+, a positive ion, as it is in group 2.
Elements in group one of the periodic table; Lithium, Sodium, potassium, rubidium, caesium and rubidium, will form ions with a positive charge of one.
We haven't seen your graph. However, it is easy to say what kinds of ions elements form. Metals form positive ions and nonmetals form negative ions.
Positive.
A positive ion and a negative ion.
A positive ion and a negative ion.
A positive ion and a negative ion.
A positive ion is formed when an atom loses one or more then electrons.

sodium
Magnesium will form a positive ion during ionic bonding. Sulfur will form a negative ion during ionic bonding. In ionic bonding, metals form positive ions and nonmetals form negative ions.
N and P for example. Nitrogen will form a N3- the nitride ion.
