How did Bohr prove that an atom must exist?

How did Bohr prove that an atom must exist? Answer: Doctor Neil Bohr in 1913 put forward the Bohr model of atom. This model fully explains the structure of atom and prove that atom must exist and it consists of basic fundamental particles. According to doctor Bohr model revolving electrons in an atom does not […]

How can you prove that angular momentum is quantized?

How can you prove that angular momentum is quantized? Hint: Let angular momentum (mvr) of 1st orbit is mvr = nh/2π By putting the values of h and π.   Answer:  Angular momentum is quantized means that electrons revolve with an angular momentum in orbits of fixed energy .For electrons of each and every orbit angular momentum […]

Isotopes – Isotopes of Hydrogen, Uranium Carbon and Chlorine

ISOTOPES: The atoms of an element that have same atomic number but different mass number are known as isotopes. “OR” The atoms of an element that have same number of protons and electrons but different number of neutrons are called isotopes. “OR”  Atoms of the same element having same chemical properties but different chemical properties are called isotopes. […]

ELECTRONIC CONFIGURATION

ELECTRONIC CONFIGURATION: The distribution or arrangement of electrons around the nucleus in various shells and sub shells according to their increasing energy is called electronic configuration. Explanation: The electrons fill the shells in order of their increasing energy that is lower energy level is occupied first then the higher energy level and so on.

BOHR’ S ATOMIC THEORY

BOHR’ S ATOMIC THEORY: In 1913, NEIL BOHR presented another model of an atom which was based on MAX PLANK’S QUANTUM THEORY. According to BOHR ‘S model , revolving electron in an atom does not absorb or emit energy continuously. The energy of a revolving electron is Quantized as it revolves only in orbits of […]
