The attraction between positive ions and surronding mobile electrons forms which type of bond?
Nope, its FALSE :)
The interaction between charged objects is a non-contact force that acts over force of attraction between two balloons that are charged with the opposite type.
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Chemists call such intermolecular forces of attraction van der Waals forces. (This also occurs in the phenomenon known as Hydrogen-bonding.) What is the alternate of a slight attraction - it is called the covalent bond. Note that an ionic bond is a type of covalent bond.
ionic bond
90 degrees angles or right angles.
The electrostatic attraction between oppositely charged atoms (ions) is termed an ionic bond
An ionic bond is the attraction between oppositely charged ions. Ionic bonding is a type of chemical bond.
The force of attraction or repulsion between two magnetic materials.
Hydrogen bonds are one of the weakest bonds, and aren't even true bonding of molecules, but rather a magnetic attraction between them. This particular bond is what allows the base pairs of DNA to properly link, as Adenine and thymine bond, and cytosine and guanine bond, but neither of these pairs bonds with elements from the other pair in this way.

Bonding is essentially electrostatic attraction between ions.
The reason why it is advantageous to have weak hydrogen bonds between complementary base pairs and strong covalent bonds between phoshate and deoxyribose groups in a DNA molecule is because the strong covalent bonds running along the "ladder" of the DNA molecule (the phospate and deoxyribose units) keep the molecule together during its existence and more importantly its reproduction. The weak hydrogen bonds in the middle keep the reproduction cycle going on forever because it is able to perform an easy split between the hydrogen bonds throughout the middle of the molecule.
Nope, its FALSE :)
All substances experience attraction between their particles. These vary in type and strength. If there were no forces they would never form liquids or solids. You could say that the strongest bonds are in the substances with the highest melting points.
