Question

which element does this bohr model represent? silicon aluminum magnesium cobalt

Explanation:

Step1: Count the number of electrons

In a neutral atom, the number of electrons equals the number of protons (atomic number). From the Bohr model, count the electrons in each shell. The first shell has 2 electrons, the second has 8, and the third has 4. So total electrons \(2 + 8+4=14\).

Step2: Relate to atomic number

The atomic number of an element is equal to the number of electrons in a neutral atom. Looking at the periodic table, silicon (\(Si\)) has an atomic number of 14.

Answer:

Silicon
