which of the following is the correct bohr model for silicon, si? 14 si 28.09
Answer
Answer:
The first option (the one on the left - with 14 protons ($p^{+}$) and 14 neutrons ($n^{0}$) in the nucleus and 14 electrons arranged in electron - shells).
Explanation:
Step1: Identify atomic number of Si
Silicon (Si) has an atomic number of 14. This means it has 14 protons in its nucleus.
Step2: Determine number of neutrons
The mass number of Si is approximately 28.09. Since mass number = number of protons+number of neutrons, and number of protons = 14, number of neutrons is approximately 14.
Step3: Arrange electrons in shells
The first shell can hold 2 electrons, the second shell can hold 8 electrons, and the remaining 4 electrons go in the third shell for a total of 14 electrons which is consistent with the atomic number. The first option shows 14 protons, 14 neutrons and the correct electron - shell arrangement.
