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

What is the best description of the carbon-carbon bonds in ethene C2H4?
Two sp2 orbitals overlap to form a sigma bond, and two 2p orbitals overlap to form a pi bond.
What is a sigma bond Describe with the aid of a diagram how the overlap of two half filled 1 s orbitals produces a sigma bond?
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
What bond forms when two atomic or hybrid orbitals overlap to form a single bond?
This is the basis of Organic Chemistry. An sp3 hybrid orbital can overlap with another and the result is a COVALENT bond
What bond restricts rotation about the axis of double or triple bonds?
Double and triple bonds each have another type of bond different from the initial single bond present between the two bonded atoms. The sigma bond, the initial single bond, is formed through a head-on overlap of two atomic orbitals. Rotation about this bond does not change the overlap, and so rotation is allowed.But double and triple bonds have pi bonds, formed by side-on overlap between the atomic orbitals (typically either p or d orbitals). These bonds surround the sigma bond and were rotation to occur, the orbitals involved with the pi bonds would cease to overlap and these bonds would be broken.Therefore, the specific bond that restricts rotation about the axis of a double or triple bond would be the pi bond(s) involved.
What is a sigma bond Describe with the aid of a diagram how the overlap of two half-filled 1 s orbitals produces a sigma bond?
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.
A bond forms when two atomic or hybrid orbitals overlap to form a single bond A bond forms when two p orbitals overlap in a double or triple bond?
sigma, pi
What two atomic orbitals or hybrid atomic orbitals overlap to form the c equals c bond in ethene?

What means p bond?
A p bond is the result of the sideways overlap of two parallel p orbitals.
What is covalent bond theory?
A covalent bond forms when the orbitals of two atoms overlap and a pair of electrons occupy the overlap region is called covalent bond theory

What is the difference of a sigma bond and a pi bond?
A sigma bond is the end-to-end overlap of the bonding orbitals, usually hybrid orbitals. The sigma bond is a single bond. A pi bond is the side-to-side overlap of unhybridized p-orbitals. A pi bond, along with a sigma bond form a double bond. sigma bond is used in hybridization but pi bond when dealing with saturated molecules is not used,that is double bonds.The oygen molecule is sp hybridized have you ever reasoned or found out why.
Ethyne C2H2 contains one carbon - carbon triple bond What is the best description of this bond?
Overlap of one sp2 hybrid orbital on each atom to form a sigma bond and a p orbital on each atom to form a pi bond.
How can you tell when atoms bond based on the valence electrons?
If I understand the theory correctly, then it is safe to assume that any molecular bond is based on the valence system. Valence bonding occurs when orbitals of electrons are slightly overlapped. Your question should rather be 'what kind of valence bond occured in the bond. There are 2 types namely sigma and pi. Sigma bonds occur when the orbitals of two shared electrons overlap head-to-head. Pi bonds occur when two orbitals overlap when they are parallel (wikipedia). So it is safe to assume that any bond that is covalent can be described using valence theory.
