The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

Scientists have finally glimpsed chemistry at its smallest level after capturing the first-ever X-ray of a single atom. Atoms are the tiniest particles in our universe, and they're the basic ...

In an advance they consider a breakthrough in computational chemistry research, chemical engineers have developed a model of how catalytic reactions work at the atomic scale. This understanding could ...

SP hybridization occurs when one s orbital and one p orbital from the same atom combine to form two new orbitals of equal energy. These new orbitals are linearly oriented 180 degrees apart, leading to ...

Excited atoms under a high energy level, termed as Rydberg atoms, possess exceptional characteristics (e.g., size and dipole moment), which are contingent on their principal quantum numbers. Despite ...
