a sigma bond is a one to one bond that is the weakest type of bond. the two filled orbitals form a single bond to hold the two elements together
Sigma bond is nothing but the overlap of half filled atomic orbitals along the nuclear axis. In the case of two half filled 1s orbitals... the electrons approch each other as well as repells... because of nucleus(attraction) and the other electron(repulsion). so they stay in the middle of these two opposing forces and forms a bond so called sigma bond.
pi bond
Two sp2 orbitals overlap to form a sigma bond, and two 2p orbitals overlap to form a pi bond.
sigma bonds.
True.

pi bond
sp2 hybrid orbitals overlap.
The side-by-side overlap of p orbitals produce a pi bond. In the field of chemistry, pi bonds are covalent chemical bonds.
sigma, pi
Two sp2 orbitals overlap to form a sigma bond, and two 2p orbitals overlap to form a pi bond.
sigma bonds.
True.
In methyl cation (CH3+), there are three sigma bond orbitals available for overlap with the vacant p orbital. These sigma bond orbitals originate from the three C-H bonds in the methyl group.
In molecular orbital theory, MO theory, molecular orbitals are "built" from atomic orbitals. A common approach is to take a linear combination of atomic orbitals (LCAO), specifically symmetry adapted linear combinations (SALC) using group theory. The formation of a bond is essentially down to the overlap of the orbitals, the orbitals being of similar energy and the atomic orbital wave functions having the correct symmetry.
overlapping that occurs along the orbital axis of 2 atomic orbitals is known as linear overlapping and these orbitals are called sigma atomic orbitals therefore these bonds are known as sigma bonds
