Question

lab directions: for each element below, first fill in the empty bohr model. then, use your spectrometer to view the emission spectra of that element and record it in the box to the best of your ability using colored pencils.

2\the\thelium\t4.0026

Explanation:

The problem involves elements (Hydrogen, Helium), Bohr models, and emission spectra, which are topics in Chemistry (a subfield of Natural Science). For Hydrogen (H):

• Bohr Model: Hydrogen has 1 proton (in nucleus) and 1 electron. The Bohr model should have 1 electron in the first energy level (closest to nucleus).
• Emission Spectrum: Hydrogen’s emission spectrum has specific lines (e.g., Balmer series visible lines: red, blue - green, blue - violet, violet). For Helium (He):
• Bohr Model: Helium has 2 protons and 2 electrons. Both electrons are in the first energy level (since the first level can hold up to 2 electrons).
• Emission Spectrum: Helium’s emission spectrum is more complex with multiple lines (different from Hydrogen, as it has more electrons and energy levels). To complete the task, draw the correct number of electrons in each energy level for the Bohr models and represent the characteristic emission lines (using colored pencils as directed) for each element’s emission spectrum.

Answer:

For Hydrogen (H):

• Bohr Model: Draw 1 electron in the first energy level (around the nucleus).
• Emission Spectrum: Draw the characteristic Hydrogen emission lines (e.g., the four visible Balmer series lines: red, blue - green, blue - violet, violet).

For Helium (He):

• Bohr Model: Draw 2 electrons in the first energy level (around the nucleus).
• Emission Spectrum: Draw Helium’s emission lines (multiple lines, different from Hydrogen’s pattern).
