De Broglie wavelength Google Classroom About Transcript Is it a particle or a wave? This is the question that physicists of the 1920s were asking about light. In 1924, Louis de Broglie took this question to another level as he explored how electrons - which are matter, and were thought to be simply particles - can behave like waves. Sort by:

We are asking, what would the atomic number #Z# have to be such that the distance to the nucleus from #n = 4# in a hydrogen-like atom (of the appropriate positive charge) is #a_0#, the Bohr radius. This is more of a numerical exercise than anything realistic. For a given Bohr orbit, the wavelength is given by #2pir = nlambda_e# #" "bb((1))#

We like representing these energy levels with an energy level diagram. The energy level diagram gives us a way to show what energy the electron has without having to draw an atom with a bunch of circles all the time. Let's say our pretend atom has electron energy levels of zero eV, four eV, six eV, and seven eV.

If an electron is accelerated through a potential difference of a million volts, its kinetic energy is, of course, 1 MeV. At what speed is it then moving? First attempt. (2.3.1) 1 2 m v 2 = e V

Snigdha Moitra. Science Teacher. 07/02/2018. Charge on an atom is always neutral it will never depend upon the number of proton ( which resides inside nucleus) and electrons ( which revolve round the orbit) as you all know that each and every atom has number of proton equals to number of electron and by law a positive and negative cancels each.

Answer: no it will have no charge.it would be electrically neutral! because the number of protons and electrons are equal!

Almost all of the mass of an atom is contained within a tiny (and therefore extremely dense) nucleus which carries a positive electric charge and almost all of the volume of an atom consists of empty space in which electrons reside (Figure 1.8. 1 ).

Explanation: Proton is positive, while electron is negative. Sum of both is 1 - 1 = 0. so the atom is neutral, which means it doesn't carry any charge.

1 Because atoms are neutral. – Jon Custer May 4, 2020 at 13:19 @JonCuster My bad; hydrogen ion. – jamie May 4, 2020 at 13:30 The point is that one electron and one hydrogen ion together make one neutral atom. That fixes the charges to be opposite in sign and equal in magnitude. (Now just why that occurs is a different question.) – Jon Custer
