The answer to this question is TRUE.

Rather than simply believing this statement, you can find evidence to support this claim. We can look at the length of various carbon-carbon bond lengths.

In the molecule ethane, we have H₃C-CH₃, with a C-C single bond length of 154 pm.
In the molecule ethene, we have H₂C=CH₂, with a C=C double bond length of 133 pm.

We see from this data that a double bond is shorter than a single bond. Now if we look at the structure of benzene:
H H
C = C
/ \
H-C C-H
\\ //
C --- C
H H

It appears that there are three C=C double bonds and three C-C single bonds. So you would expect different bond lengths between the double and single bonds. However, what we actually find is that every C-C bond is the same length of 140 pm. This is due to resonance, therefore, every C-C bond is actually an average of the double bond character and single bond character each bond experiences which gives us a value of 140 pm which is longer than a traditional C=C bond and shorter than a traditional C-C bond.

Answer from: Quest

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is $1s^{2}2s^{2}2p^{6}3s^{1}$ and electronic configuration of phosphorous is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}$ .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

$3na + p \rightarrow na_{3}p$

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

Electrons are transferred from atoms of to atoms of this transfer makes the sodium atoms and the
