BRD and Subatomic particles

Atomic Structure

Atom Parts

• Nucleus, contains the positive protons and the neutral neutrons
• Electron orbitals, contains the negative electrons
• The proton and the neutron are about the same mass, while the electron is about 1/2000th the mass of the other particles

Atomic Key

• Atomic number = amount of protons = amount of electrons
• Atomic mass = number of protons + number of neutrons
• Neutrons = atomic mass - atomic number

Maximum number of electrons in each orbital

• Orbital 1: 2
• Orbital 2: 8
• Orbital: 8
• Orbital 4: 18

The subatomic particle other protons that can be found in the nucleus are called neutrons.

Hydrogen doesn’t have neutrons
