The parts of an atom.
An atom has three particles, and the names stick once your kid knows where each one sits and what charge it carries. Study Butler builds the picture from the center out.
Here is what that looks like.
Study Butler will not print the answer. It points at the next step and lets your kid take it.
An example. The butler answers the question with a question.
what is in the nucleus of an atom.
two of the three particles live there. the electron is the one that does not. so which two are left.
protons and neutrons.
good. now which of those carries a charge, and which is neutral.
Where students get stuck.
The same few mistakes come up again and again. Here is where the butler slows things down.
01Mixing up the three particles
Proton, neutron, and electron blur together. Study Butler ties each to its charge and location, which makes them distinct.
02Putting electrons in the nucleus
Electrons orbit outside the nucleus, not inside it. The butler has your kid place each particle deliberately rather than lumping them together.
03Confusing atomic number and mass number
One counts protons, the other counts protons plus neutrons. Study Butler keeps the two counts separate with a clear question.
Bring the problem they're stuck on.
Type it, say it, or snap a photo. Study Butler walks your kid to the answer one question at a time, so they learn it instead of copying it.
