Which of the following describes a double bond between two carbon atoms? 1 a double bond will produce four single bonds to form a tetrahedral shape. 2 a double bond between carbon atoms will eventually form a ring of carbons. 3 a double bond between carbon atoms is longer than a triple bond between carbon atoms. 4 a double bond will quickly reduce to single bonds to create three-dimensional tetrahedrals.

The correct answer is Option 3.

Explanation:

Carbon atom is the 6th element of the periodic table. The valence electrons of this element are 4. This element requires 4 electrons to attain stable electronic configuration.

This element can form single bond, double bond and triple bond will the same element that is carbon.

If more number of bond are formed between the atoms, it means that the bond strength of that bond will be more because the orbitals come closer to each other.

And bond strength is inversely proportional to the bond length.

Thus, single bond will have the lowest bond strength and highest bond length.

Then, will come double bond which has more bond strength than single bond and shorter bond length than single bond.

Then, will come the triple bond which has more bond strength than double bond and shorter bond length than double bond.

Order for bond length follows:

Hence, the correct answer is Option 3.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
