The sigma bonds are formed when orbitals overlap side by side and is related to covalent bond In ethylene the number of sigma bond are 5.
Reason, carbon has four carbon -hydrogen bond which form four sigma bond. The other sigma bond is between carbon=carbon bond thus ethylene has 5 sigma bond
It is an alloy <span>made of copper, magnesium, manganese, and aluminum.</span>
For an atom to be neutral the protons and the electrons should be equal.
Therefore the number of protons are 5
So A is the answer.
I’m not sure but I think it’s Earthquake Detector
