Want this question answered?
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.
The question does not make sense. LCAO takes a linear combination of atomic orbitals from the atoms, some orbitals are not energetically favourable to produce bonds (*other exclusions are symmetry) and these do not form bonding orbitals.
That is related to the relative positions of the orbitals involved.
Linear Combination of Atomic Orbitals. It's basically a technique which represents molecular orbitals as a sum of the atomic orbitals of each the atoms making up the molecule multiplied by some coefficient (the coefficient can be, and in fact generally is, different for each of the atomic orbitals involved).Any good text on Quantum Mechanics (one of my favorites is Quantum Chemistry by Levine) should contain much more detail on the subject.

the element futher down a group
It is the number of protons found in the nucleus of an atom. It is represented by Z.
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

The different orbitals are s orbitals, p orbitals, d orbitals, and f orbitals.
A commo approach is LCAO, linear combination of atomic orbitals. This gives rise to molecular orbitals and is a technique with particular strengths in determining bond energies rather than bond location. For exampel a simple moleculae such as methane in MO theory is predicted to have four bonding orbitals- where one has a lower energy than the other three and this is borne out by spectrocopy. this is a different insight to that provided by traditional valence bond theory which predicts four equivalent bonds to hydrogen.
LCAO linear combination of atomic orbitals is a technique used in molecular orbital theory. He refers to an ATOM helium. Atoms do not have bond energy. The question as asked is meaningless
