Compare the mineral halite (NaCl, hardness of 2.5) to diamond which is pure carbon chemically bonded to itself in a network. Are the mineral's chemical bonds covalent, polar covalent, or ionic? Which mineral is harder?
On Mohs scale, isn't diamond assigned a $10$ on the basis of hardness? Halite is almost a purely ionic material.

What is different between an ionic bond and a covalent bond?
Ionic bonds are bonds between two who has a large difference in . For instance Sodium chloride: $NaCl.$ Sodium have a low electronegativity and chloride have a very high electronegativity....

What is the difference between a polar covalent bond and a nonpolar covalent bond?
The electronegativity of the atoms involved in a covalent bond determines which will have more pull on the electrons shared between them. Because all atoms have different electronegativities, the only...

What is the difference between a nonpolar covalent bond and a polar covalent bond?
Non polar covalent bond is the bond formed between two similar atoms in which the Electronegativity difference is zero eg - H---H While in polar covalent bond , there is...

I do not understand ionic bond is non directional but covalent bond is directional ?? Please explain me easy ways. Thank you.
Our basic notion of stems from the transfer of electrons to form positive and negative ions. Each positive ion, each cation, is electrostatically bound to EVERY anion, each negative ion...

Describe the uniqueness of a covalent bond. How is it similar to an ionic bond? How is it different from a covalent bond?
Both bonds result in forming of differentiating properties and structures. Atoms react in order to achieve stability. However, covalent bonds have a unique property that ionic bonds do not...

Consider the following element combinations. Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent qualitatively based solely on each element's position on the periodic table? Do not conduct calculations.
Something worth knowing about deciding between nonpolar and polar is that only two of the same element can form an ideally nonpolar bond. With this in mind, the $"Br"-"Br"$...

What symbols are used to represent the charges on atoms in a polar covalent bond? The polarity of the bond? boble type of bond?
Where the $delta$ symbol denotes a little bit of (or partial) positive or negative charge. Dipoles are drawn from positive to negative. The overall dipole moment is the vector sum...

How do you determine if a molecule has a polar covalent bond based on the lewis dot structure?
In a covalent bond the electrons are shared between both atoms, in a roughly equal manner. If the electron structures for both atoms are stable after sharing they will share...

In terms of a $P-Cl$ bond in a molecule of $PCl_5$, why it is more polar than a $P-S$ electron bond in a molecule of $P_2S_5$?
As mentioned above, one must consider the difference in the electronegativities of the two bonded atoms. Chlorine is somewhat more electronegative than sulfur. Since electronegativity is designed to provide a...
