Atom
What is the positively charged center of an atom that contains protons and neutrons and is surrounded by a cloud of electrons called?
Nucleus
This particle is negatively charged and it surrounds the center of an atom.
Electron
This particle is positively charged, composed of quarks, and is found inside the nucleus of an atom.
Proton
This particle is has a neutral charge, is composed of quarks, and is found inside the nucleus of an atom.
Neutron
These are particles of matter that make up protons and neutrons.
Quarks
This is the area around the nucleus of an atom where the atom's electrons are most likely to be found.
Electron cloud
This represents the number of protons in an atom's nucleus.
Atomic number
This represents the sum of the number of protons and neutrons in an atom's nucleus.
Mass number
These are atoms of the same element that have different numbers of neutrons.
Isotopes
This is the weighted-average mass of the mixture of an element's isotopes.
