How are atoms represented?
Atoms are represented as…
Atoms are represented as empty spheres, which contain a nucleus and an electron cloud around it
*contain a nuclues and an electron cloud
True or False
The total charge of an atom is not neutral
False
What is the electron cloud?
The electron cloud is the…
The electron cloud is the outer shell of an atom where electrons orbit in
Why do electrons remain bound to the positevily charged nucleus?
Thanks to the electromagnetic force
What is the nucleus held by?
The nuclear strong force, which attracts protons and neutrons
What is the nucleus formed by?
Nucleons
Define
Nucleus
The nucleus is the central part of the atom and is formed by nucleons
