ATOMS all living things are made from atoms - they're really tiny and too small to be seen (even with a microscope). each atom is made from small particles nucleus of an atom contains protons and neutrons. trons have the same /equal amount of rela- 3 the + PROTONS will always have a positive charge (a way to remember •p= positive, p = proton.

I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D
Philip, iOS User
The app is very simple and well designed. So far I have always found everything I was looking for :D
Lena, iOS user
I love this app ❤️ I actually use it every time I study.

negatively charged and they're tiny, but they cover alot of space, electrons have virtually . no mass. a neutral charge 10 charge because they have the the charge electrons, atoms are neutral, they have Overall. They have no charge same amount of picions and On the electrons is the same size as the charge on the protons (there is the same amount of protons and electrons in an atom, and when you take them away from eachother, their charge becomes neutral. 0 in an ion, the number of protons and neutreas electrons isn't the same as the amount of electrons so it has an overall charge over 0 (unlike on atom which has a with it's charge neutral charge), as an example, an ion - 2-` has 2 more elections than protons. an ion is an atom or a group of atoms that has either lost or gained electrons - hence why an ion has an ove- rall charge.
