Question

Natalie observes these characteristics in the model of an atom. (i) includes positive charge (ii) contains electrons (iii) explains the photoelectric effect (iv) suggests the probable location of electrons

Answer 1

Natalie is observing electron cloud model of an atom.

What is electron cloud model?

• The electron cloud model is a representation of an atom that has a small, massive nucleus that is encircled by a cloud of electrons that are traveling quickly.

• According to the electron cloud model, although we can never be certain of an electron's precise location, it is more likely that they are in certain regions.
• It is created by Erwin Schrodinger.
• Due to the uncertainty principle, the electron cloud model establishes the zone of probability describing the electron's location.
• The electromagnetic force pulls the electrons of an atom toward the protons in the nucleus.
• The electrons are constrained by this force inside an electric potential well surrounding the smaller nucleus, therefore an external energy source is required for the electron to escape.
