Atomic Structure

Subatomic particles with a positive charge

• neutrons
• atomic mass
• protons
• isotopes

Value representing the number of protons in an element

• Atomic Mass
• Mass Number
• Valence Electrons
• Atomic Number

Subatomic particles that are neutral in charge

• Neutrons
• Protons
• Nucleus 
• Electrons

Atoms of the same element with a different number of neutrons

• Ion
• Gluons
• Isotope
• Quarks

A charged atom

• Ion
• Isotope
• Electron Cloud
• Quark

The smallest particle of an element that shows all the properties of that element.

• Subatomic Particles
• Atom
• Quarks
• Gluons

A tiny but very dense, positively charged portion of the atom that holds most of the atomic mass

• Electron Shells
• Orbitals
• Electron Cloud
• Nucleus

Created the Planetary Model of the atom

• Bohr
• Dalton
• Rutherford
• Chadwick

Calculation used to find the number of neutrons in an atom

• Atomic Mass - Atomic Number
• Atomic Number - Atomic Mass
• Atomic Mass - Electrons
• none of these

True or False - Protons and Neutrons have about the same mass.

• True - They have about the same mass
• False - They do not have about the same mass
