Question

draw the bohr model for si

Explanation:

Step1: Determine the atomic number of Si

The atomic number of silicon (Si) is 14. This means a neutral Si atom has 14 protons in the nucleus and 14 electrons.

Step2: Apply the electron - shell filling rules

• The first shell (K - shell) can hold a maximum of 2 electrons.
• The second shell (L - shell) can hold a maximum of 8 electrons.
• After filling the first two shells (2 + 8=10 electrons used), the remaining 14 - 10 = 4 electrons go to the third shell (M - shell).

Step3: Draw the Bohr model

• Draw a nucleus and label the number of protons (14).
• Draw three concentric circles around the nucleus to represent the K, L, and M shells.
• Place 2 electrons on the K - shell, 8 electrons on the L - shell, and 4 electrons on the M - shell.

Answer:

A nucleus with 14 protons (labeled as 14). Three electron - shells: the innermost (K) shell has 2 electrons, the middle (L) shell has 8 electrons, and the outermost (M) shell has 4 electrons.
