- Label the atom diagram:
- Nucleus
- Proton
- Neutron
- Electron
- Electron shell
- Fill in the table for subatomic particles:
- Proton: Name = Proton, Charge = +1, Location = Nucleus
- Neutron: Name = Neutron, Charge = 0, Location = Nucleus
- Electron: Name = Electron, Charge = -1, Location = Electron shell
- Complete the tables for each element:
- Fluorine (F): #P = 9, #N = 10, #E = 9, Atomic # = 9, Mass = 19
- Copper (Cu): #P = 29, #N = 35, #E = 29, Atomic # = 29, Mass = 64
- Calcium (Ca): #P = 20, #N = 20, #E = 20, Atomic # = 20, Mass = 40
- Fill in the blanks:
1. An atom of nitrogen contains 7 protons.
2. The name of the element with 10 protons is Neon.
3. Helium contains 2 neutrons.
4. The atomic mass of sodium is 23.
5. Iron contains 26 protons, 26 electrons, and 30 neutrons.
- Complete the tables for atoms practice:
- Helium: #P = 2, #N = 2, #E = 2, Atomic # = 2, Mass = 4
- Lithium: #P = 3, #N = 4, #E = 3, Atomic # = 3, Mass = 7
- Sodium: #P = 11, #N = 12, #E = 11, Atomic # = 11, Mass = 23
- Draw electrons and fill in information for Carbon, Beryllium, and Aluminum:
- Carbon: # of electrons = 6, Atomic # = 6, Atomic mass = 12
- Beryllium: # of electrons = 4, Atomic # = 4, Atomic mass = 9
- Aluminum: # of electrons = 13, Atomic # = 13, Atomic mass = 27
Parent Tip: Review the logic above to help your child master the concept of atoms worksheet.
