The highest energy occupied molecular orbital in the C-C bond of the C₂ molecule is 2pπ orbitals.
<h3>What is Molecular Orbital Theory?</h3>
According to this theory,
- Molecular orbitals are formed by intermixing of atomic orbitals of two or more atoms having comparable energies
- The number of molecular orbitals formed is equal to the number of atomic orbitals combined.
- The shape of molecular orbitals formed depends on the type of atomic orbitals combined
- Only atomic orbitals having comparable energies and the same orientation can intermix
- Bonding M.O. is formed by the additive effect of atomic orbitals and thus, has lower energy and high stability.
- Antibonding M.O. is formed by the subtractive effect of atomic orbitals and thus, has higher energy and low stability.
- Bonding M.O. is represented by
while Antibonding M.O. is represented by

Answer:
Chemical properties can be recognized only when substances react or do not react chemically with one another, that is, when they undergo a change in composition. A chemical property of one substance usually involves its ability to react or not react with another specific substance.
Electrons in their ground state when excited absorb energy and move to higher energy states.
Absorption is when energy is absorbed by electrons and they move to a higher energy state
Emission is when electrons release that absorbed energy and move to a lower energy state
This release of energy results in emission of light from a flame
The correct answer is
Release energy as they move to lower energy states
An isotope is the vary of neutrons in an element, causing its atomic mass to change. While an ion is a charged atom that bonds to be stable.
Answer:
Cs and I
Explanation:
Salts are formed when an ionic bond is formed between two elements in the compound. Let us recall that the kind of bond formed between any two elements depends on the magnitude of electronegativity difference between the two elements.
Among the options listed, the highest degree of electronegativity difference occurs for the bond between Cs and I. This implies that this bond is ionic and the combination of the two elements will lead to salt formation.
