Which of the following statements about hybridization are true? Select all that apply: Hybrid orbitals exist in isolated atoms.
Leokris [45]

Answer:

True:

  • Hybrid orbitals within the same atom have the same energy and shape.
  • Hybrid orbitals are described mathematically as a linear combination of atomic orbitals.
  • An atom can have both hybridized and unhybridized orbitals at the same time.

Explanation:

Hybrid orbitals do not exist in isolated atoms. They form only in covalently bonded atoms.

Hybridization happens when several atomic orbitals combine to form other orbitals with the same energy and greater stability.

A set of hybrid orbitals is generated by combining atomic orbitals. The number of hybrid orbitals in a set is equal to the number of atomic orbitals that combined to produce the set.

Hybrid orbitals overlap to form σ bonds. Unhybridized orbitals overlap to form π bonds, and both can appear in an atom at the same time.

how do we know that all the continents were all together at one point in time. writing prompt and it has to be at least 7 senten
kari74 [83]

Answer:

We can tell by how the continents look. Scientists who propose the pangea theory have said this. You can see for yourself because all the continents look like puzzle pieces you could put together. Scientists can also tell from the species. For example, let's say a scientist found a bone of a creature at the edge of a continent, the edge of another would have the same species. They have also calculated that the continents in itself are still splitting apart, but very slowly. The reason they split up was because tectonic plate movements.
