What symbols are used to represent the charges on atoms in a polar covalent bond? The polarity of the bond? boble type of bond?

On Mohs scale, isn't diamond assigned a $10$ on the basis of hardness? Halite is almost a purely ionic material.

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...

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...

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...

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 $"Br"-"Br"$...

The modern covalent bond is conceived to be a region of high electron between two positively charged atomic nuclei such that nucleus-nucleus repulsion is negated, and a net attractive forces...

We could represent the hydrogen chloride molecule, which is certainly polar, as $""^(delta+)H-Cl^(delta-)$. Electron is polarized towards the more electronegative atom. Is this what you wanted?

The answer is (C) have polar covalent bonds with a partial negative charge on the hydrogen atoms. If you only go by the options given, the answer will be obvious...

Take carbon tetrafluoride, $CF_4$; the $C-F$ bonds all show charge separation in that fluorine polarizes electron density towards itself (i.e. a $C-F$ bond is polar!). Nevertheless, if we take the...

We know that $1*mol$ contains $6.022xx10^23$ individual sodium atoms, and has a mass of $22.99*g$. And thus for $1.$ there is a $2*g$ mass of $Na$. For $2.$ there is...
