Which group in the periodic table tends to form ions with a 2 charge?

An element should release two of its outermost electrons to obtain +2 ion. The elements in group 2A are the most likely elements to have this configuration. These are known as Alkali Earth Metals.
The elements in the 2nd group have 2 valence electrons. Elements give away their valence electrons to get stable electron configuration. The elements in the 2nd group such as beryllium, magnesium, calcium, strontium, barium likely to have positive ion with charge of 2.
Group II elements (the alkaline earth metals). This is because this particular group of elements have two extra electrons in their electronic configurations. They need to lose these two electrons to attain the stable noble gas configuration. So they will have a tendency to lose them to other atoms or group of atoms, in the process incurring a double positive charge (since there will now be two less electrons than protons). So Be, Mg and Ca will all form positive ions (cations) with a charge of +2. They are represented by Be2+, Mg2+ and Ca2+ respectively. But, other elements like copper and barium will also form cations of charge +2.

But two ions, each having a charge of +1, would not combine to make an ion having a charge of +2, because they would repel each other. Positively charged ions combine with negatively charged ions to make neutral compounds.

Be, Mg, Ca, Sr, Ba, Ra
These metals all form ions with a +2 charge and enter into ionic

Does fluorine tend to lose electrons?
Fluorine is a nonmetal. It is located in group 17 of the periodic table. It tends to obtain an electron to form the fluoride ion.Fluorine is the element with highest electronegativity. So it does not tend to lose electrons. It is in the 17th group of the periodic table.
What groups of elements on the periodic table tends to form ions?
Alkali metals group tends to form ions.They give single electron to gain positive charge.For example : Sodium give one electron to become Na+ ion.
Which family tends to be chemically unreactive?
The noble gases, column 18 in a wide form periodic table.
How does chemical reactivity change as you move down a column on the periodic table?
It tends to increase. As you go down a group, the outer electron gets further away from the nucleus and is thus not held as tightly which makes it more available and thus reactive.
What group of elements tends to form negative ions that have a -1 charge?
Group that tend to form -1 ions include group VIIA
Which group on the periodic table tends to have seven valence electrons?
halogens or group 17

. How does atomic radius change from top to bottom in a group in the periodic table?
It tends to increaseThe atomic radius increases down the group
Which group of elements on the periodic table tends to form ions?
Group one, not including element 1 (helium) tend to form ions.
What trend does the ionization energy follow in the periodic table?
It decreases when going down a group.
What atom tends to gain one electron when it combines with another atom?
All elements in the 7th family/group (2nd from the right) on the Periodic Table.
Bonding between atoms on the left and right sides of the periodic table tends to be?
ionic
What tends to gain electrons?
Elements on the right of the periodic table but not in group 0/8 tend to gain electrons. Those in group 7 tend to gain 1 electron and those in group 6 tend to gain 2.

Alkali metals group tends to form ions.They give single electron to gain positive charge.For example : Sodium give one electron to become Na+ ion.
Which category of elements on the periodic table tends to create negatively charged ions?
You are good at questions dude
Which family tends to be chemically unreactive?
The noble gases, column 18 in a wide form periodic table.

Maybe there is no pattern...no it fals
