Sally is making a model of a Mg atom with an atomic mass number of 24. She has balls for the protons, neutrons, and electrons. She has added 6 neutrons to her model. How many more …

I would go for the Rutherford Model: In this model the atom is described as a planetary system with a central massive (and concentrated) positive charge, the nucleus, and orbiting around it …

The Bohr model applies only to a hydrogen atom or to ions that contain only one electron (hydrogen-like ions). To get a hydrogen-like ion, we must remove all but one of the electrons …

We know that ionization potential or the first ionization potential is the energy required to remove the outermost electron from a neutral gaseous atom of an element. Similarly second and third …

Rutherford did not expect anything from electrons before running the gold foil experiment. The conclusions concerning the effect of the electrons on alpha particles came after discovering …

The energy of the nth Bohr orbit for a hydrogen atom, which has Z = 1, is given by the equation En = E1 n2, where E1 - the energy of the 1st Bohr orbit, equal to -1312 kJ/mol; n - the energy …

The diameter of the nucleus would be 2.62 cm. 1. Calculate the diameter of the nucleus The radius r of a stable nucleus is roughly proportional to the cube root of the mass number (A ) of …

How do increases in temperature affect the density of ocean water? Why is the modern-day quantum model of the atom better than John Dalson's model? How is the wave speed of a …

Apr 8, 2017 · Question #39e52 Chemistry Bohr Model of the Atom Calculations with wavelength and frequency

A certain atom consists of 16 protons, 18 neutrons, and 16 electrons. What is its atomic number, mass number, and electron configuration? What is atomic number? How is it used to …
