How has the development of this model influenced modern scientific research?
1) the model has influenced the development of quantum mechanics.
2) the model has allowed investigators to wrap up unsolved cases.
3)the model has allowed for the sequencing of the human genome.
4) the model has been used to understand the principles of atomic energy.

The model which is Quantum mechanical model of the atom helps to develop the development of the quantum mechanics which influenced the modern scientific research.

Option 1.

Explanation:

The model of Quantum mechanical model of the atoms makes use of complex shapes of the orbitals which are also known as the electron clouds. It also makes use of the volume of the space where there is an electron most probably.

The development of the model helps to influence the Quantum mechanics which explains the nature and the behavior of the matter and the energy on the level of atomic and at the sub atomic level. The word Quantum in this Quantum Mechanics has been taken from Latin which means "how great" or "how much".
