There are 3 isotopes of carbon. Carbon-12, Carbon-13 and Carbon-14. The average atomic mass of carbon is 12.011. Which isotope of carbon is the most abundant? Why?
The relative of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass...

Carbon has a third isotope, named carbon-13. How many protons and neutrons are found in each atom of carbon-13. Carbon-13 is a stable isotope, like carbon-12. How useful would carbon-13 be for radiometric dating?
This is called the of the element. To make it up to 13 in carbon-13, you will need 7 neutrons. Stable isotopes are not useful at all in radio-dating,...

From a consideration of the Lewis structure of the thiocyanate ion, SCN–, in which carbon has a double bond with both the sulfur and nitrogen atoms, what are the formal charges on the sulfur, carbon, and nitrogen atoms?
As is typical we put the least electronegative atom in the middle...and we gets Lewis structures of.... $N-=C-S^(-)$, else, $""^(-)N=C=S$. And thus the negative charge is conceived to lie on...

Is the bond between two different atoms that share electrons equally called a polar bond?
Polarity describes charge separation. If a covalent bond is polar, then electron is shunted to the more electronegative atom. If electron density is shared equally, e.g. in $H_2$ or $X_2$,...

An oxygen molecule contains a double bond because the two atoms of oxygen share a total of how many electrons?
A covalent bond is conceived to result from the sharing of two electrons between 2 positively charged atomic nuclei. A $sigma$ bond results where the electron is precisely between the...

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...

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...

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...
