All of the Group 2 elements, the Alkaline earth metals, want to lose two electrons and form an ion with a +2 charge. And of these elements, it is radium that is the most reactive. Radium wants to lose its two valence electrons more than any of the other elements of its group.
Remember that reactivity increases as we move down the groups on the left side of the Periodic Table (with one exception). These elements each wish to shed their valence electron(s) and form an ion. In the case of the elements in Group 1 of the table, the Alkali metals, they wish to shed their single valence electron to end up with a +1 charge. And caesium, which is the second-to-last element in that group moving down, is a bit more reactive than francium, which is below it. That's the lone exception to the rule.
When we consider the elements of Group 2, we find that radium is the most reactive, as we've already stated. It (radium) is at the bottom of the Group 2 elements.

∙ 11y agoaround all elements except those which had attended a stable electronic configuration can form ion.ions are actually the charged atoms formed due to the gain or loss of electron by it.positive ions are formed by loss of electron due to which the number of protons(positively charged sub atomic particles) becomes more than the numbers of electron(negatively charged) and it is called cation.
similarly,in case of anion(negative ions) it is opposite of the above.

What element forms a 3 plus ion with ten electrons?
Aluminium, Al
Period 3 element that forms a 3- ion?
The third period element that forms a 3- ion is sulfur.
Which element forms a 3 plus ion that has the electron configuration Kr4d6?
Rhodium (Rh) forms a 3 plus ion that has the electron configuration Kr4d6. Rhodium has oxidation states of 2,3 and 4, so it can loan out 2, 3 or 4 electrons depending on the circumstances of a chemical reaction.
If a plus 1 ion has 29 protons what element is it?
copper
What is a charge particle that forms when one or more electrons are transferred from one element to another?
It is called an Ion.

What Element z forms an ion Z3 plus which contains 13 proton?
S
The element that forms a 2 plus ion with the same electronic configuration as Ar?
Calcium
Period 3 element that forms a 3- ion?
The third period element that forms a 3- ion is sulfur.
What is a period 4 transition element that forms a 2 plus ion with a half filled d sub level?
Manganese
Which element forms an ion with the same charge as the ammonium ion?
potassium
Which element forms more than one ion?
The ion is awesom
When an element forms a negative ion what happens to its name?
When an element forms a negative ion, the name changes to IDE, fir example: chloride
Which element forms a 3 plus ion that has the electron configuration Kr4d6?

What compound has the 2 plus ion that is the smallest with a filled d subshell and an anion that forms from the smallest halogen?
Ni2+, Goes from having 28 electrons to 30, giving it 10 electrons in its 3d subshell making that subshell full.
If a plus 1 ion has 29 protons what element is it?
copper
What is a charge particle that forms when one or more electrons are transferred from one element to another?
It is called an Ion.
