What is a BR diagram?
Bohr-Rutherford diagrams are simple atomic models that show the number of electrons in each shell of an atom. While they are a major simplification of what really happening in an atom, they can be useful to help with visualizing electrons orbiting a nucleus.
What is the electron configuration for K?
[Ar] 4s¹
Potassium/Electron configuration
What is atomic number for K?
19
Potassium/Atomic number
How many neutrons are in K?
20 neutrons
The element of potassium has the symbol K. The nucleus of an atom of potassium contains 19 protons and 20 neutrons.
How many neutrons does BR have?
45 neutrons
a) How many neutrons does the atom of bromine have? The mass number = protons + neutrons. Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons.
What is the electronic configuration of K19?
K19 = 1s2 2s2 2p6 3s2 3p6 4sx. Mn25 = 1s2 2s2 2p6 3s2 3p6 3d5 4sy.
What is the neutrons for Br?
a) How many neutrons does the atom of bromine have? The mass number = protons + neutrons. Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons.
What are the chemical properties of BR?

What is the difference between Rutherford model and Bohr model?
Since the Bohr model is a quantum-physics-based modification of the Rutherford model, many sources combine the two: the Rutherford–Bohr model. Although it challenged the knowledge of classical physics, the model’s success lay in explaining the Rydberg formula for the spectral emission lines of atomic hydrogen.
What is the Bohr model of the electron?
In this view, electron orbits around the nucleus resemble that of planets around the sun in the solar system. The Bohr model was an improvement on the earlier cubic model (1902), the plum-pudding model (1904), the Saturnian model (1904), and the Rutherford model (1911).
How many protons and electrons does BR have?
Symbol: Br Atomic Number: 35 Atomic Mass: 79.904 amu Melting Point:-7.2 °C (265.95 K, 19.04 °F) Boiling Point: 58.78 °C (331.93 K, 137.804 °F) Number of Protons/Electrons: 35 Number of Neutrons: 45 Classification: Halogen Crystal Structure: Orthorhombic Density @ 293 K: 3.119 g/cm 3 Color: Red Atomic Structure
