The permanents are ionically bonded to the hair because the ionically bond is stronger. Which allows the permanents to stay permanent.
Intermolecular forces are weaker than covalent and ionic bonds. Covalent bonds involve the sharing of electron pairs between atoms, making them strong and stable. Ionic bonds involve the transfer of electrons from one atom to another, creating strong electrostatic attractions between oppositely charged ions.
Ionic bonds, metallic bonds, and covalent bonds are all types of chemical bonds that hold atoms together. They differ in terms of the way electrons are shared or transferred between atoms. Ionic bonds involve the transfer of electrons from one atom to another, metallic bonds involve a "sea" of delocalized electrons shared between metal atoms, and covalent bonds involve the sharing of electrons between nonmetal atoms.
The relative strength of bonds is: Covalent > Ionic > Metallic > Hydrogen Bonding > Van der Walls Dispersion Forces This is only a general, as there are ionic substances that are quite strong, and relatively weak covalent substances. The strongest substances are network covalent, which includes diamond and, strangely enough, graphite. lie in general the ionic bonds are stronger than covalent bonds
Ionic Bonds-form when two atoms have a large difference in electronegativity. Covalent Bonds-form when two atoms have a very small difference in electronegativity. Polar Covalent Bonds- form when two elements bond with a moderate difference in electronegativity. Fall between ionic and covalent. Metallic Bonds-form in and between metals
Ionic (e.g. sodium chloride etc.): highmelting/boiling points. Ionic bonds (electrostatic attraction between oppositely charged ions) must be broken to break the ionic lattice and form a liquid/gas. Ionic bonds are strong so lots of energy is required.Giant covalent (e.g. diamond, graphite, silicon dioxide): high melting/boiling points. Covalent bonds (shared pairs of electrons) must be broken for the substance to become a liquid/gas. Covalent bonds are strong so lots of energy is required.Simple covalent (e.g. water, hydrogen, ammonia, bromine): low melting/boiling points. Although covalent bonds are strong, they do not need to be broken in order to separate molecules and the substance become a liquid/gas. Only weak forces between the molecules must be overcome, which does not require much energy.

A covalent bond involves the sharing of electrons between atoms, resulting in a strong bond. In contrast, an ionic bond involves the transfer of electrons from one atom to another, creating a bond between oppositely charged ions. Covalent bonds are typically formed between nonmetals, while ionic bonds are formed between metals and nonmetals. Ionic bonds tend to be stronger than covalent bonds due to the attraction between opposite charges.

covalent compounds --------- It is inadequate to discuss about a telephone in terms of ionic and covalent compounds.
In valence bond terms pure covalent bonds are only possible between atoms of the same element, any ionic resonance forms are "symmetric" and contribute equally to the structure. In the case of ionic bonding the covalent resonance forms that contribute to the overall bond do not cancel in the same way, they may however be of a sufficiently different energy to the "pure" ionic resonance form to make only a minimal contribution to the overall bonding.
The answer to this question is somewhat strange. Calcium Bromide is an Ionic compound therefore the terms polar and nonpolar don't really apply because there is no bond. There are however two completely different charges between the atoms therefore making it, in a sense, the strongest kind of polar molecule- an ionic polar. So Calcium Bromide is Polar.
A telephone receiver is not a compound itself, but the materials used to make it can be either ionic or covalent compounds. The components of a telephone receiver, such as plastics and metals, are typically made of covalent compounds.
Bid bonds will protect the owner of the project if the bid is not honored, performance bonds will guarantee the work will be completed according to the terms, and payment bonds will guarantee all payments that are due from the principal. These are the three types of construction bonds.
