What is a molecule? How do you identify one?
A molecule is a group of atoms, and is usually represented by a group of letters and numbers, like CO2 or H2O
What is the amount of neutrons in the nucleus of an atom that has the atomic number of 41
52
An atom has 3 protons. How many electrons are there?
3
Why don't protons and neutrons move with electrons when static electricity forms?
Electrons are much lighter, and are already outside of the atom
Magnesium is the 12th element on the periodic table. It has 12 neutrons. How would its atom look?
