where in the periodic table are elements found that will always form ionic binds?

Question

i meant bonds

Answer 1

that question is impossible to answer full because the type of bonds depend on which two elements are reacting. however, we might take the left side of the table (metals) as most of thier reactions are ionic. though when pure they have metallic bonds :)

Answer 2

Ionic bonds involve the formation of ions, which are atoms that have a charge. This occurs when an electron(s) moves from one atom to another, which causes an electrical imbalance. The reason electrons would move from one atom to the other is based on their stability as far as their own electron count is concerned.

The more unstable atoms are out on the outer edges of the periodic table (excluding the most right-hand column which is the nobel gasses, the most stable atoms on the table). The elements on the left side of the PT want to get rid of extra electron(s) and those on the right side of the PT want to gain them. This makes them especially good at forming a variety of salts which are ionic compounds.

This can be seen quantitatively by looking at a PT which shows electronegativities (EN) for the elements. The greater the difference between two atom's EN the greater ionic character of the bond between them.
(Low EN difference leads to covalent bonding, or the sharing of electrons between the two atoms)

Answer 3

In the first left column beginning by hydrogen (alkali) and the first column at the left of the noble gases beginning by fluor (halogens)
The alkali tends to give an electron yielding positive ions. The halogens tends to win an electron giving negative ions

The columns at the right of alkali give also positive ions as the colums at the left of alcal give negative ions. However the tendency is lower tha alkali and halogens

Answer 4

The Halogens in Group IA.
