Multiple Choice
A Bohr model shows a nucleus with 6 protons and 6 neutrons, surrounded by two electron shells: the first shell contains 2 electrons, and the second shell contains 4 electrons. Which element is represented by this Bohr model?
A
Boron
B
Carbon
C
Oxygen
D
Nitrogen
Verified step by step guidance1
Identify the number of protons in the nucleus, as the number of protons determines the element's atomic number. In this case, the nucleus has 6 protons.
Recall that the atomic number corresponds to the element's position on the periodic table. An element with 6 protons has an atomic number of 6.
Use the atomic number to find the element's name. The element with atomic number 6 is Carbon.
Verify the electron configuration given by the Bohr model: the first shell holds 2 electrons, and the second shell holds 4 electrons, which matches Carbon's electron arrangement (1s² 2s² 2p²).
Conclude that the Bohr model represents the element Carbon based on the number of protons and the electron configuration.
